i'm black and i agree happen to agree with kathy griffin...black people and any member of a minority group have every reason to hate trump with the white hot heat of a thousand suns.
there's only ONE reason for which i can forgive hart for not commenting on trump...and that would be that all the other stand-up comics do a trump routine, so maybe there's a lack of fresh material out there...but even so, if you're a good comedian you find ways to put a unique spin on it.
but i don't think it's all about the fact hart is black...there's MANY reasons to hate trump besides the fact he's racist against black people and brown people. Trump is also a misogynist....and a xenophobe. He's also a lying, dishonest, scumbag, blowhard, egomaniac. A dumbass who knows nothing about nothing except that "mexicans bring crime and rape" and blacks who protest peacefully are "SOBs"...he even believed muhammad ali needed a pardon, obviously because ali was a black man and why would a black man not need a pardon, after all he MUST have been in trouble with the law, right?
griffin is simply saying that minority groups who have been offended and attacked by trump are natural allies in the resistance against the rise of trump-led american fascism. therefore, if you're a black person or a woman or a human being with a sense of morality, and you have a platform that allows your voice to be heard, you have an OBLIGATION to speak out against this enemy of the people...so, IMO she's absolutely correct in her criticism of hart, and well within the bounds of reason to do so.
