Ok lemme defend this one:

It's probably just a manifestation of The Crazy...but maybe not.

At a time when people are pretending to be the opposite sex, and some are even undergoing extreme medical treatments up to and including hormone treatments, puberty blockers, and amputation / reconstruction of sex organs...you can't be too careful. Just because someone looks male and claims to be male, that person could be female. 

So, yeah. We live in clown world. That sign is pretty likely to be a manifestation of the clown cult worldview...but it might instead be a reaction to it.
