I mean, do they not realise how fucking stupid that looks?

It's not just the muslims, either:

It seems that the only thing these guys have in common is religiosity... They don't even subscribe to the same brand of fruitloopery.
Does it say somewhere in The Book Of Derp "Thou shalt grow thy beard to a luxurious length, but thou must shaveth thy moustache, to declare your membership to the Holy Brotherhood of Fuckwit."?

Is it some kind of equivalent to the Freemasons' funny handshake? A way for them to recognise each other?

Discuss.
