If an aggressive coach is too much for a boxer, how will he stand up to an aggressive opponent? The guy in the ring when you fight is trying to hurt more than your feelings.
If he's teaching you how to box, he's doing a good job. If he's swearing and abusive to everyone he teaches, there's no need to take it personal. That's not to say you have to put up with it. You can quit and find a trainer who doesn't shout abuse, and hope he knows his stuff too.
