you see the joke here is that quote "drags (who are pedos, mind you) are invited to read books for children; doomguy kills demons for a living and the feathers atop the head are meant to resemble a demon"
the triangle here is a symbol allegedly used by pedophiles to identify each other which has led to boulderchuck thinking *every* instance of a swirl design is "pedo-code", thus another "trans are pedos" joke
