I understand your argument and agree with you in certain aspects, however, I don't think you used a good example.
Jonah Hill aggressively calling someone a faggot is offensive. It implies that being a 'faggot' (commonly considered to mean homosexual) is a bad thing. Like he is criticizing the guy for being homosexual. That is an insult to all gays.
I'm a big fan of Jonah Hill and love that he went on to make an extremely heartfelt apology for it.
Well the paparazzi was referring him to as 'sexy' and other sexual sayings. Much like if the westboro baptist church was yelling at you saying you're going to hell cause you're an atheist and you turn around and say 'Fuck off you religious psycho'. In the same way jonah hill was being sexually harassed. Jonah understandably knew the guy was saying it to get a rise out of him. So the sexual calls eventually got to him. Seeing the person was sexually harassing him he mockingly 'embraced' the sexual suggestions by what he said.
I don't feel his apology was genuine, he's a comedian. The characters he plays are in no way PC. I feel it was simply a Public Relations tactic to smooth over the issue. I have no direct evidence of that though.
If you watched the video I talked about another example. When I was in 6th grade I was being harassed by a group of about 10 8th graders. Every day they would tease me by coming up behind me and lifting me up and tossing me, calling me names, criticizing anything I wore, criticizing me for being quiet, they'd hit me, they'd shove me. I went to the teachers, they did nothing. One day one of them came up behind me at recess and punched me from behind, knocking me to the ground, then he proceeded to kick me in the stomach over and over. I was just walking outside, didn't have anything to do with him, and he did that.
So yeah one day after months of this going on and nothing happening, I said to one of them who was black "why can't you leave me alone you fucking n-word" and I don't regret it. I was tormented by these assholes and yeah I tried other options but I had no other choice, because once I said that, the kid left me alone. But apparently it hurt him so much he went to the principal who was also black and yeah the issue was I used the 'n-word' and not that these kids would attack me, torment me etc.
So with Jonah Hill, yeah he's constantly harassed by the paparazzi and I can understand yelling at these people. Granted my situation was probably worse simply because it was physical attacks, but harassment is harassment.
