Racism can be defined different ways. But the one that racism groups people's into higher and lower quality is the traditional one. I do not fully agree with that, for me, racism already begins where exclusion happens even if one does not act for the sake of superiority. There are also those who take it for racism when a white person isdressed up like an native American on carneval or for a costume party or a white person has dreadlocks that is often done by minority groups but this is a form of racism for me because it is a political power lever to control the whites and because exclusion happens, exclusion of whites, for example, that in a left-safe space white heterosexual men are not welcome, also diverse means that there are not many whites. So this is also a form of racism. If whites exclude non whites we anyways consider it racist and I agree with that.
