They're more interested in imposing it at gunpoint. They are one of the main sponsors of terrorism.
If this is your idea of covering up for your ignorance, you're not making it any better.
One of the main sponsors of terrorism (and just as importantly the main sponsor of fundamentalist mosques in countries where a more relaxed brand of Islam is traditional, from Bosnia to Indonesia, thus potentially breeding "homegrown" terrorist groups in countries where this otherwise wouldn't have been an issue) is Saudi Arabia. Funnily enough, that's no reason to break ties with them, while Iran doing maybe (if that) one tenth the funding of extremism counts as good enough to paint them as Satan?
Saudi Arabia has been getting better about it. Iran has been getting worse.
