Its Muslims right to worship as they see fit.
Of course it is, as long as they remain a strong enemy of America, that is.
You leftists don't mind if your allies butcher homosexuals. You don't really support rights for gays or anyone else, you just seek to undermine American cultural values. You don't mind if Muslims beat, mutilate, and murder women. You don't really support women's rights, or any rights for that matter.
Leftism is a fraud, the ONLY goal is total power. If a system of pure evil assists you in the goal of subverting constitutional liberty, you're all for it.
Personally I think the idea of worshipping some deity is riduclous, regardless of the religion. I do support peoples' rights to worship as they see fit, however.
But if Al Qaeda can help you turn America into North Korea, then you'll bow to the Idol in Mecca. The goal of totalitarianism transcends petty objections to deities.
The pact between you leftists and radical Islam is just like the one between Hitler and Stalin. Bummer we can't just sit back and watch you destroy each other.
