It's a shame this person is a parent. It's also no wonder he's divorced.....
The solution seems really simple to me. You speak to the rink, and based on his behavior, you get him banned from attendance. Period. He can still drop his daughter off for practice, but he's not allowed inside at all.
I'm not sure where the disconnect is, to be perfectly honest. People are too cordial and accepting of asshole behavior. He's breaking public health orders. He's breaking USA Hockey guidelines. He's breaking the rules of the rink. He's breaking the rules of the club. He's putting the entire club in jeopardy with his actions. f*** him. He's a selfish f***ing loser, and should be banned from the rink until he shows that he can FOLLOW THE RULES, like any functioning adult does. This guy is a piece of shit, and I would not feel bad in the least about reporting him to all levels of authority, including USA Hockey. If he gets a USA hockey suspension or a ban, good. He deserves it.
I just recently did exactly the above with a fellow coach, who was also a COVID denier, and knowingly putting the kids at risk with his behavior.
Rules are rules, and they are there for a reason. I'll be damned if I let a single individual ruin it for all of the kids I coach, and the families who support those kids. He honestly deserves an ass kicking, and people that behave in this manner, have typically never had their ass kicked. I'll be perfectly honest. There's about a 5% chance that I wouldn't have beat the ever living shit out of this guy already.
