There isn’t white culture.
There isn’t black culture, or Asian culture.
Culture doesn’t come from skin color. Seriously, take a basic human geography course. Culture is based on where you’re from and how you’re raised.
So, yeah, you can’t erase the culture of millions of people- the Poles, the Italians, the Swedes, the Russians- because you’re a whiny SJW. And there can be white people raised in an African culture, or Hispanic culture.
Culture isn’t exclusive to skin color. I don’t know why you think that.
