That reminds me of the X-Files episode "Humbug" about a disjoined twin that goes on a killing spree in a town populated by circus freaks and sideshow performers.
I know the humor thread. I read an article on free thought. It said free thought was not just inside your mind, but must be shared out in public or socially to qualify in post liberal times. Yet some thoughts were dangerous and free thought also required limiting thought for safety. The conclusion being just about what this sign says. We include everyone and should, genuine free thought is not possible otherwise, and for safety your thought might need to be excluded.
