(Warning! This will probably sound manipulative and honestly, it might be. But keep in mind, this comes from the mind of someone with high-functioning autism, which means a lot of my understanding of social mechanics is on a conscious, rather than subconscious, level. This isn't a foolproof guide to brainwashing the masses; it's a list of general guidelines (which are probably faulty) from someone who learns about interacting with people successfully in the same way they learn how to play chess successfully. I'm not advocating lying or manipulating people to get what you want. This is (supposed) to be a presentation on what I've learned about how you should choose to present yourself and your ideas so that your audience is more receptive.)
I actually deal with a similar (but less severe) issue with gay rights stuff. Thankfully, it's less of a touchy subject, but I've learned the hard way that I'm one poorly worded comment from a large pile of downvotes. Here's a list of 10 things I've learned:
1) The most important thing is to play devil's advocate at all times. If you don't seem impartial to the general community, then you will polarize opinions against you, and that almost never works out in your favor. Additionally, if you really aren't being impartial, then what metric are you using to judge your arguments as being correct? In other words, if you can't sincerely admit the possibility that you are wrong, then how do you know your argument is logical in the first place?
2) You need to be patient. There will be times when you will feel like people are being hypocritical, or irrational, but harping on the issue will often make it worse. And I can guarantee you will receive undeserved down votes and logical fallacies thrown at you. If things like that make you feel sad or angry, then it's probably best you back out. Remember, there are people just waiting for you to "slip up" and reacting in such ways is like providing a big, blinking red button on a giant robot to the video game protagonist fighting it in a boss battle. And take people seriously, whether that means repeating the same counter-argument to same popular misinformed stance for the 100th time to someone new, or if it means replying to a joke by someone you get along with in an appropriate manner, instead of being rude or just ignoring them. Remember, your fellow users are people.
3) Learn when to hold your ground, and when to back out. This is one of the most subtle lessons, but one of the most important, since it really has an impact on how people see you, and by extension, your ideas. If you don't acknowledge criticism, then people are less likely to take you seriously and you miss out on opportunities to "gain ground". On the other hand, if you always have to have the last word, then people may think you are the kind of person who will never admit they are wrong. And don't automatically delete something you posted previously, just because it doesn't seem particularly popular; doing so without discretion tends to give off the impression that you are being manipulative and care more about how popular your ideas are more than how much confidence you have in them being logical.
4) Don't treat the community as a means to an end. Remember, most people are here to discuss memes and such, so don't force the issue where it isn't relevant. If someone brings it up first, then feel free to go ahead (though tread lightly.) If the item of discussion is directly relevant, then go ahead with more confidence. If you can tie in the item of discussion to something you want to bring up, and do so skillfully, then feel free to take the risk, but only occasionally. And don't just hang around for your topic of interest. Engage with the more popular parts of the website. Being seen as a "real" member of the community carries a lot of weight with it.
5) Learn to accept defeat. Nobody's perfect, including yourself, the people with whom you argue, nor the people just watching you go at it with your detractors. Logic doesn't always win the day, and trying to get things back on that track may end up doing more harm than good in some cases. If this happens, do not overreact and don't try to change other people; instead, just end your participation and wait for another chance to say what you want in more favorable circumstances. Not to mention it's unlikely that everything you post ever will be logical, but I covered that already.
6) Stretch yourself to engage with others in different ways, and learn when each is most effective. In a lot of ways, socialization is a lot like battling in RPGs, where certain strategies work best in certain situations. Being blunt works well in some cases, where subtlety is key in others. Humor can be a great help in one situation, and hurt you the next, in which case being somber would have been a better option. The list goes on and on, with things like brevity vs. precise articulation, confidence vs. a self-effacing attitude, being open about your opinions, experiences, or ideas, vs. choosing not to divulge them, etc. Also, keep in mind which of these are used most often by those who you have interacted with frequently, both by friends and not-so-friends, so you know how best to work with them or avoid being messed with.
7) Be consistent in your message. Generally speaking, nobody trusts people who are hypocrites or double-talkers. Think about how you feel on issues and stay consistent with them as long as you are convinced they are logical. This change in arguments should not happen often, because if it does, then that indicates you are easily swayed (and thus your judgements cannot be trusted) or are lying about being swayed (in which case you are manipulative.) Like I said before, be open to other arguments but make sure you have a firm belief in it in the first place before arguing it out in the open.
8) Always double-check and spell check. Not only will you find simple grammatical errors or spelling mistakes, you may find that what you read is different than what you thought you wrote. Also, people are less likely to take you seriously if you \/\/r173 |1k3 7|-|15.
9) Be knowledgeable in your subject. Use the Google news search on your topic and keep up with the events regarding it; make sure to save anything you feel would be important or useful in the future. If you are extra proactive, read about any sources and/or studies mentioned in said news stories and/or in the sources of Wikipedia pages related to your study.
10) Be knowledgeable in general. You can be the expert in your idea, but if people think you are sheltered, then you will have to work to get them to listen to you in the first place, generally speaking. Chiming in when you know something will signify to people that you are learned and have common sense. Additionally, learning things may help in unexpected ways. For example, logical fallacies are one of the few things that nearly everyone on the internet gives some respect to, as an argument or a point of contention. Using textile, and providing sources not only looks good, but it makes people more likely to read what you write. Knowing when to use semicolons and when to use "who" or "whom" isn't just fancy, it's useful.
Hope any of this helps!
