Do you find Americans are way too sensitive about race?

I think it's a very tense topic in America, mainly between white and black people. I don't really understand it, but it seems to be a whole "thing". Perhaps black and white people tend to live in different areas, and that causes a division? But it's probably far more than that. I've never been to America myself, but I see videos from America on the internet of course, and I honestly don't remember it being as big of a topic over there when I was younger, I think it has gotten worse?
