My thing is, if MJF is willing to do that, then don't act surprised when a pissed off fan claps back and all hell breaks loose in the future. That's the kind of thing those antics are looking for anyways, to have that kind of "heat", so either stop it right there or live with the consequences.
I think AEW did enough with that kid so that people can leave it alone though, it wasn't a fireable offense in my book.
