Pretty much agree with #-3's point and the higher levels of PeeWee and Bantam having hitting.
My argument is purely anecdotal, but from my 6 years coaching Div 1 and AA Bantam, the size difference of kids at that level scares me when neither of them know how to make or receive a hit. I've had players that are 5'0 and 100lbs soaking wet, and players that are 6'2 200lbs. Even with the way was, the speed these kids play at, there were times I would cringe. I couldn't imagine what would happen if that 6'0 kid thought it was ok to slam his forearm into the 5'0 kid's head. It happens sometimes, it's a contact sport and kids can be dumb. But in my opinion it will happen with more frequency as an accident with the rule change, rather than the odd kid who does it on purpose.
Of course removing hitting from PeeWee will lower the number of injuries in PeeWee, my concern is harsher injuries at a higher level when there's more speed and size discrepancy between kids.
On top of that, it's a sport. No different than football, or lacrosse, or rugby or whatever, people WILL get hurt playing a contact sport. It's inevitable. If you don't want your kid to take the risk don't let them play, or sign them up for non-contact (plenty of options there). If non-contact isn't competitive enough, well the hitting is part of the competitive side of it, sorry.
Every kid has to go through PeeWee and Bantam. The kids in the top divisions should be taught the entire game.
