They can have a festival for female genital mutilation and a forum to discuss bomb making.
To be entirely fair on the female genital mutilation issue, I don't think it is a Muslim religious custom exactly, but rather more of a cultural custom in some parts of the world where Islam is practiced.
I think its barbaric and insane (and in fact, I now refer to our friends in the mid-east exclusively as 'those posturing, chest-thumping rejects from Lord of the Flies'), but the genital mutilation thing isn't partcularly religious.
It is, of course, insane.
