Are the Liverpool players going to wear shirts in support of Suarez again?
It was properly, properly mental.
A Hannibal Lecter mask would be more appropriate.
On the other hand, if the consideration is the possible damage Suarez could have done, it's relatively minimal. Assuming he doesn't have any STIs (!), he's never going to end Ivanovic's career by doing that, and will probably cause less damage than a full blown punch or two footed challenge. From that perspective, it's violent conduct, three match ban, everyone moves on.
It has nothing to do with potential damage that he could have done and everything to do with what is this crazed lunatic doing to do next. Maybe he will go all Mike Tyson and bite someone's ear off?
