OP: AIBU?
Most of MN: YABU!
OP: Waaaahhhhh! Bitches! I'm getting my thread deleted!
And then nowadays you just delete for them & say "This thread has been deleted at the OP's request. (We don't normally delete whole threads but we will do so when it is to protect a poster's privacy.)" regardless of whether that's actually true.
You really need a new message that says "This thread has been deleted at the OP's request, because they threw a tantrum and we don't need the hassle."
