I guess I'm just not woke enough to find any humour offensive. Some stuff just isn't funny, but nothing offends me, I'm not offended by comedians who have to rely on untrue tropes to try and make a gag. They're just poor comedians, their inability to make a decent joke isn't offensive its just a reflection of them being shit.
Tropic thunder is 100% funny, even the black face.
The video makes a Chinese people might be offended by a character mangling mandarin. Why, it just shows a lack of skill at mandarin. Same with the jack black Fatties in film piece. It's not like Jack Black is supermodel thin. Tasteless is funny, it's awkward and painful. As long as its not bullying in tone.
