Blind, bitter hatred isn't a good reason.
Wenger is biased, of course. So are all managers. So are all (proper) fans.
Mourinho, who you fawn over, completely embarrassed himself on Saturday by sarcastically congratulating the referees for conspiring against him

. Had Wenger said something that stupid you'd have had a field day. In this interview he was asked about the Arteta incident, Bruce (biased towards his own team) had said it was a foul and the resulting goal changed the game. Wenger pointed out it was miles from their goal - so they should have had time to get back and cover - and in any case
he didn't think it was a foul (the MoTD pundits agreed so you can hardly say that opinion is a case of Wenger's bias.
Wenger irritates you just by breathing. It was a good performance, a good result and a perfectly reasonable comment. There was nothing negative to say so in desperation you made up something. It's pathetic.
EDIT: The irony it it's actually you who has lost all sense of objectivity. Your blind hatred of Wenger is so strong you can't tell the difference between Wenger making a perfectly reasonable comment and a stupid one (which he does sometimes, but I'd suggest no more than most managers)
