Actually, let me prove it's a textbook case. You can find a similar example provided by SE at https://support.na.square-enix.com/f...la=1&kid=68216
This is a list of the sort of comments SE would not approve of.
  • "If you can't do the mechanic well, maybe you shouldn't bother joining the party."
  • "If you're going to talk like that, why don't you just quit?"
  • "If you don't understand that, you'd be wise to leave the party."
  • "Let's ignore them."
  • "Let’s leave [person] out."
  • "It's not worth wasting our time, you should quit."
  • "Don't join if your equipment is that bad/such a low item level."
