Religious zealots, irrespective of what they worship, are abhorrent and barbaric. And yes, that is not confined to muslims only, it includes some self righteous christians too (and jews and scientologists etc).
On the muslim issue however, many muslim nations are not tolerant of anything other than Islam. How do they expect then that the rest of the world is required to tolerate them when they don't tolerate others? Especially when they go to foreign countries and require that everyone else conforms to what they want.
