How has it expanded in a way that you disagree with? Cuz as far as I can tell it's at it's most distilled "Fucking with people for shit that is inherent to their person".

The reason that your examples are allowed is because hate is viewed within context of our society and history. If you think that racism against white people or sexism against men has been significantly problematic ever you're pretty ignorant.

As soon as white men are under threat of subjugation or discrimination in any significant way I'll agree that those phrases should be banned. Until then they are only offensive and not harmful.
