I understand it's a bit taboo, but he would've said something similar to anyone, it wasn't because of Muma's sexuality. Should he have been more careful with his wording, of course but this is a bit much, Muma acknowledged there was no malicious intent behind it and accepted his apology. I also don't know if it's true but supposedly he found out by DF's announcement, which if true is baffling for a team with such low squad morale already
Of course it isn't my place to say whether he deserves more or less punishment, but I think what's not being recognized is how snide it was.
Personally I think what he actually said was pretty mild, but the fact that he tried to act like it was an accident is pretty annoying, basically pulled an r/oopsididntmeanto. It's childish and passive aggressive, pretty typical among NA gamers, especially pros.
