Whatcha Think Joe Kelly

Alright baseball peeps - what do you think about this suspension? I haven't played since t-ball and have therefore always been a little out of the loop on the unwritten rules/norms of baseball (I've always thought the uproars over bat-flips or staring at home runs or whatever way overblown and puzzling).

If they suspended him over the inside pitches only based on his history - I'd get that. But it seems they suspended him for making "you're a big baby" faces. I mean, that's arguably pretty childish, but is it something that should earn a suspension?
