I agree, but there becomes a point where a lot of people have tolerated a lot for so long, seeing nothing change, and they have had enough.
I don't particularly like the way some supporters have gone about it, and I agree some of it is childish, but If this discontent hadn't been shown this season and even last season, then Wenger wouldn't even be thinking about signing a new contract, because he would have already signed it.
I think the boot is now on the other foot.
I've lost count of how many times anyone who dared to question Wenger or the board were told, "go and support another club," or "you're not a real supporter."
This might be the reason a lot of them are just copying what was done to them.
