Don't try to defend the undefendable with other examples.
Bale did dive and as a Spurs fan i don't like to see that.
Call me biased, but nobody in the present EPL does it like Suarez does (remember the derby last season how he got Rodwell a red card, that is something you don't do to a colleague). One could argue about the Man Utd player who came from Aston Villa (sorry, but i can't remember his name, age does that to you), but his general attittude is not like Suarez. It seems like Suarez really tries everything to be not liked.
One can give examples of Suarez' unfair attitude every single match. Believe me or not, i used to love him as aplayer, until i saw him week in week out...
Is this subjective? Without a doubt but if loads of people have the subjective feeling that a player behaves badly, then this becomes a fact. Just try to imagine him with exactly the same attitude in a Man Utd shirt and you would hate him with a passion dags..
It's one to support your club, but just a litle bit objectivity will do no harm.
