A bully like that is the same bully that will deny a kid transferring if he is worth anything.
Honestly, I don't worry about the cursing/homophobia/insults. Ppl are stupid and you will hear that no matter who you are if you interact with ppl enough.
However, that rough ridin' coward kicked a kid and threw god knows how many balls at ppls heads over the last three yrs.
I am even ok with they way he grabbed jerseys and stuff. Make the ball throws hard passes to the chest when you have the kids attention, and I would be fine with that too.
Dive bombing them like that and kicking to add extra emphasis is way over the line though and ppl that don't understand that were raised wrong.
