>Why is it happening, and why is it unique to the yellow flag?
I wouldn't say it's unique to their flag but you are right about the matter. To be fair, you have some Protestants (Baptist or otherwise) who have done the same. There was that one guy who who made a thread false-flagging as an Orthodox ranting about war crimes committed by "Catholics". >>832317
What can you do about though, OP? They probably do it because to not contest would be remiss, in their eyes, to God in saving souls from heresies/heretics. They might also be remnants of the mod mafia, though I thought I read in /meta/ that they flocked to Tudor's discord where they can do as they please.
