As usual, you are out of touch with reality. Do you think he really elbowed her in the head in any meaningful sense right in front of her husband and camp if there were absolutely no repercussions even threatened? Do you think he actually made a real threat to assault her when he was talking about her statements and the statements of all her fans that she would beat in him a fight? She started that shit, and he just said the obvious truth about what would happen if they fought. He shouldn't have even responded to it, but it was the day before Miesha's fight with her and they get a lot of hate from the rabid Ronda fans. Comparing what he said on twitter to what Gus did is laughable.
Yeah, he tried to cover his mouth, which is legal, as well as pull Perez' face back with his jaw, chin, etc, which is also legal. It's real technique for getting a RNC.
I can understand why there is such dislike for the guy: people like you with pretty much no critical thinking skills.
