For the same reason why men aren't clubbing bytches on the head and dragging them to their homes.
There are still undertones of "rape culture" as some people call it where open sexism and generally rapey behavior is socially unacceptable, but it's still a thing. Those attitudes still persist, you just receive more backlash for them than you would have generations past. White kids used to stand around at lynchings eating ice cream comes while black bodies were swinging from the limbs. Somewhere a long the line, even racist whites determined that that shyt was a bit much, who's cleaning this up?
You keep scaling that down and this what you have. Like I said I'd rather have transparency, but there is no going back to that. Even whites who hold those attitudes don't want to mess that comes with letting their less tactful friends put it all on front street. It's bad for business.
