Not really, I think it's more self-hate. Kind of like a school shooter mentality of resentment.

I never used to hear the argument until recently, but I've heard A LOT of Leftists making the argument: "I wish I had been aborted."

It comes down to the obsessive Rousseau-ian concept that every restriction on your will is a form of oppression against you, even to the point of nature tyrannizing you with gravity. If someone already has significant emotional problems adopts a left wing ideology that promotes catastrophizing problems, you're going to see them start making arguments on that are very anti-human, and very anti-life in general.
