It's players' perogatives for who they play with, who they talk with, and such. There are actions you can take on your own, such as blacklisting, not partying with, not allowing in an FC, and such. And yes, if someone displays horrible behavior, it should be brought up to a GM. I understand as well that GMs can't particularly do much about what happens outside of the game (although there are cases, such as one I remember where someone harassed someone over parses). Which is why you take your own steps that you are not only allowed to but encouraged to take in order to keep your community clean.
It's as simple as: I like FFXIV, but I don't need to follow every single FFXIV topic and read every forum post. It's toxic. I try to read and uplift encouraging and positive stuff; and in this case, my whole original point is to:
1) Not fight over who's more toxic, but to support eachother
2) Recognizing actual toxic behavior and making it clear that it's not welcome here
3) Recognizing that if someone is not welcoming of someone with a history of toxic behavior, that does not mean they are a gatekeeper
All of these were said by me without reference to The Current Topic Man because they have been coming up in conversations in regards to The Current Topic Man. If Asmon is fine, then he's fine. He's shown prior behavior that's iffy, which is why people are allowed to curate their spaces how they want and are able, and should be able without being harassed for it. If he comes in and has no problematic behavior, nice. Unfortunately, he's bringing in a following that everyone has agreed shows that toxic behavior. They aren't fully his responsibility, but he should do everything to set them straight if he hasn't already. I say this as having followed a few bigger streamers who don't have audiences like this because they have zero tolerance for bigotry.
Does that make sense? Or will you just respond "not your choice it's gm" again, kind of ignoring the whole point?
