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.
It was someone named LiberalSocialist who argued that sufficiently older people dating younger people were still doing something potentially wrong even if the younger person was old enough to be considered an adult.
The argument had some validity, I think, especially because older and more established people (especially in upper echeolons of society) do have more power and sway over people, say, less than half their age and can manipulate and hurt them more easily, but over time, LiberalSocialist started saying "Power Dynamics" on its own as an argument stopper and kind of a self-made meme.
Thanks!
