You are entirely justified in not swallowing your alienation to ugly, pointless, embarrassing, aggravating behavior like what you describe those folks engaging in.

Rejecting that doesn't make you screwed up.

But the conversation you describe doesn't suddenly become less ugly, pointless, embarrassing, or aggravating if these people had instead been being arguing the same way about, say, hypothetically losing billions of dollars, or hypothetically moving from Beverly Hills to Bangladesh, or hypothetically swimming the English Channel.

That is, I don't think the event you're describing justifies the conclusion you're trying to use it to justify.

That said, I also don't think you actually care about that.
