Sarcasm is an adjusted stress reaction.

Less awesome parts of fandom wonder how a blind woman can have a child.

Seriously? Do they think the uterus has some special connection to the eyeballs? Do they imagine the baby's in some quantum state where if you're not observing it emerge it will vanish in a puff of logic? Have they severely misunderstood the term "eye-fucking" and drawn vastly inaccurate conclusions about where babies come from?

Or is it something more boring like "Disabled people aren't really sexual, and also can't be expected to be parents ever"? It's the boring one, isn't it?
