A whole lot of nothing.
Why should we let people say things they shouldn't be saying. If they can't say it in public without consequences.
You can personally ignore it in your now Realizdd Mute Filter, and Blacklist the player.
Or you can be like the rest of us, and actually report BS.
But no one should have the right to speak without consequences. (You're free to speak. But not what it causes to people to react. for good or bad. That's just naturally always gonna occur.)

As for your whole WoW Vs XIV spiel.
No one truly believes it, and most that do say things like that. they do it as a joke, or to raise their mood over other things.
and that has no relevance with the person you responded to was talking about.
In short a strange form of "Strawman"?
As someone who keeps asking for alt friendly implementations, Glamour System Overhauls.
It's strange that you even bring it up, as if it isn't something we all care about. but don't mention it otherwise. unless it's a thread dedicated to it.
