Okay okay. Culture is a description of what people do. Tradition is what people do that they have done for generations. There isn't too much of a divide between the two.
But culture goes far beyond what funny clothes you wear when you celebrate national holidays. It's more then just the food you eat and your bone structure. It is a way of living, an unwritten code of conduct that teaches you what is right an wrong, and what you should do with your life.
Your traditions can support bigotry, OR they can vehemently oppose it. Some peoples or nations have long had cultures of equality and caring. Others, not so much. If you look at ancient civilizations and say: wow, they were cruel, you are only reflecting YOUR OWN culture because that is where you got your definition of cruelty.
If you feel like culture is "outdated" or "morally wrong", it's because your culture is shifting. You are merely looking at a culture you don't belong to.
What may seem good to one person may seem bad to another. Latin Americans are more touchy, whereas white European Americans prefer a wider personal space (of course this can differ from person to person). Neither is bad, but one may seem impolite if not understood by the other. This is a largely unimportant example, but it illustrates that people see things in a very different light, and what is okay to one person could be abhorrent to another.
Some traditions we can recognize as being a good influence and a bad one at the same time. In the U S of A, we have a long standing tradition of questioning authority and bucking the system. That's good and bad: it spurred the American Revolution and the Civil Rights movements but also lynch mobs and paramilitary cattle farmers.
If we have traditions we don't like, should we try to change them? That question has been asked by every generation of young people since time immemorial.
