With football being a contact sport,I think lungeing or two footed tackles are more accepted as being part of the game with appropriate punishments for bad fouls usually being meted out.
Although a Suarez bite comes nowhere near the pain threshold of a Roy Keane crunching tackle,I find it odious the same as spitting,elbowing or attempted gouging.
I'm not saying Suarez should be banned for 2 years or anything like that but maybe a dozen games with the premise he has to undertake behaviour counselling.
Also,it should be pointed out to him in no uncertain terms,that if he does the same again he will face an automatic years ban and be forced to sign a long term contract with Plymouth Argyle on his return.....if that doesnt sort him out,then nothing will !
