I guess you mean legal consequences, so mostly none. There are words that should carry penalties, like if someone orders to kill a person, technically that's only words. But in this case, as far as I know, this guy didn't say anything like that so none, nothing at all.

But a different thing is putting myself, and many other people I care more about than this bloke, in harm's way to protect him from the consequences, even if unjust, of the things he said.
