Your hypotheticals are very weak. In general, the black people that espouse “you can be racist against whites” are highly educated, right wing grifters.
Now, if we mean a poor uneducated black man that’s saying shit like “you can be sexist against men,” then I’d fucking be shutting that shit down in the same way. Either you go educate yourself, or you stop spreading your shitty opinions
No, I believe they need to shut the fuck up and stop saying shit that’s oppressive or they need to educate themselves on the oppression of women/gays/transpeople/whatever
Is it systemic oppression that’s limiting the poor uneducated black man? Should you silence the poor uneducated black man? Are you not a party to said oppression when you attempt to silence someone for being “dumb” and “uneducated”? Do you not have the faculty of mind to be helpful? To understand the plight of the poor uneducated black man, from your position of privilege and wealth, even?
