Randomly popped into my head this morning
I challenge the people on this site to this task: Come up with a reasonable and convincing argument for an opinion that is the exact opposite of yours, I'm not saying you have to completely change your views to be in this discussion, however I'm mainly asking you to empathize and challenge said views when it comes with people who have the opposite or different opinion on the matter.
It doesn't have to be political per-say, it can be about more minor things [like praising movies you don't like or criticizing a game you really like], I simply think this is a good practice in challenging ones views & empathy
