People from any and all cultures do this, I have personally experienced it from black and white

Depending on how you're going about this, you might find you'd be too, in their shoes?

> I don't think there's much stronger way of bringing about racism than actually getting to know and see other cultures

Then I think you need to go and have a real think about things. Also this sentiment is just not backed up by the data - if anything, more insular societies tend to be more racist/xenophobic than open ones. Ofc not everyone in either society shares the same sentiment, and for the open ones it depends on the cultures in question and how the integration is being handled. But in general it just sounds like you've opted for a more bigoted approach, which is your choice I guess.
