Black Lives Matter has been demanding racially segregated "safe" spaces. This is racism. And if you're going to try and define racism as some power plus prejudice nonsense, you've become so racist that your very definition of racism is racist.

Of course racism does do a lot more damage when those kind of beliefs are held by a powerful majority over a minority, but race based discrimination, even when advocated for by a minority of a minority like BLM is still harmful, evil, and wrong.

Racist groups like BLM believe and constantly try to convince every one else that everything is about race, and that members of the "oppressed minority" will never be able to get ahead in life because of the ever present amorphous all powerful "racism." The existence of this powerful magical racism becomes an article of a fanatical faith, and it is blasphemy to deny it, even where there is no evidence of racism. Every problem in your life, every institution you interact with and every person you meet becomes mired in racism in the practitioners mind.

The most unfortunate damage that this kind of race worshiping fanaticism causes is that those who subscribe to it either never try to get ahead because they've been taught that there's no point, or waste much of their time and lives "fighting racism," a battle that can never be won, for the imagined enemy is everywhere and nowhere. Society isn't racist. Racism is society. Even if you completely revolutionize and change a society, the new society will be found just as racist. And all that time spent tilting at windmills is time wasted that the cultists could have better spent actually getting ahead in a society where all have equal rights under the law.
