> It blows my mind that some people really believe that only white people can be racist. It's like they completely redefined the meaning of the word "racist".

That's the point. Redefine words so that it's impossible for someone who doesn't share their point of view to have any moral high ground.

Redefining common words makes your ideology impossible to discuss with outsiders.

That makes your followers who have adopted the new definitions fairly immune to persuasion. Some cults work like this. I've never seen it done by anyone with a defendable agenda.

Yes, they did completely redefine the term. And they hold that their definition is the only 'correct' definition; all other definitions were a mistake and it is racist to use them.

Maybe Github's words and deeds will result in a lawsuit by "white people" and we'll get this legally settled.
