Wenger might be a hypocrite some times, but he's 100% right on what he said: it was either 2 yellows or 2 reds. Takes two to tango. Gervinho didn't start that fight, it was Barton who was waaaay over the top. If Gervinho dived, let the ref deal with him, don't go lifting him like that almost ripping his shirt, that was way out of order. I've never seen in my life such an aggressive action going unpunished, he should get a straight red for starting a fight like that.
Funny thing is that cunt Barton falling to the ground like he was shot after the softest touch to his face. And he spent 1 minute on the ground like he was really hurt!
I saw Vermaelen coming to him and I thought he would do the same, lifting the cunt by his shirt and telling him to man up 
I know I would do it. I'd love to see Barton's reaction to that kind of treatment.
Truth is, Barton manipulates those idiotic Premier League refs like puppets
