When it comes to racism, sexism, and transphobia, the “dissenting opinions” are things like “you do not exist” and “you are sub human” and “you do not deserve rights.”
You’re fooling yourself if you think that not tolerating hate == stifling dissenting opinion. How should one stand up for human rights? Moderately? Or militantly?
Sounds like you’ve bought the old conservative line of bullshit on all this. “Oh they don’t permit sexism? We should be highly skeptical of this!! What about freedom of speech??”
