I'll give mine to get the ball rolling.

There was a user that, before getting banned, declared that every single living human being alive on Earth right now should not exist because no one had the benefit of a pre-conception device on hand to somehow determine each individual's consent to exist before they started to exist.

I don't know if that take would make David Benatar blush, make David Benatar cackle with glee, or if that was posted by David Benatar himself.
