> these issues have been solved a long time ago where I live

I can't think of anywhere where that is true, but perhaps you can give us examples, even of places besides where you live.

Usually I hear similar claims from people who are not directly targeted by the discrimination. They don't see it and (IME) don't want to have to deal with it.

Racism must pass endless barriers to belief. No matter how great the evidence, people seem to demand more.
