I'm gonna say something unpopular: I don't like to rush.

Except the context is different. They're pulling to speed up the run and have no intention of causing a wipe whereas you refusing to pull off them is entirely out of pettiness while knowing full well said pettiness can lead to a wipe.

Even if you subscribe to the belief pulling for the tank is rude. Allowing the party to potential wipe so you can "teach them a lesson" is far worse.

I've never said to allow the party to wipe, so I don't know what you're talking about here. It seems like you're trying to respond to other people's posts, not mine.

a single-pulling tank in an endgame roulette is widely considered a detriment to the party; They're playing in a way that is considered obstructive/slow by most players doing endgame roulettes

A slower run is not obstructive in any way, and it's not a detriment to clearing a dungeon. So your premise is false.

Still waiting on any actual reasons btw. I could jump off the edge of every normal raid I do for the first five minutes - whatever, still gonna clear, doesn't matter. The logic is clearly flawed.

Yeah, your logic is flawed. Taking yourself out of the fight and letting others complete the work for you is not the same as doing smaller pulls in a dungeon where everyone is still doing their part in the fight.
