Human garbage seems excessive, but Domi’s actions shouldn’t be defended either in my opinion. You don’t drop the glove and clock someone who clearly isn’t engaging in the fight. If you want him to retaliate, make him angry by playing hard hockey, and I don’t know, maybe scoring a few goals?
It was dirty, and should keep him out of all remaining preseason. Also doesn’t make him human garbage. He was losing, lost his temper, and made a mistake. We’ve probably all done worse.
