Yes, I'm aware of the penalties for apostasy in Iran, and that the toleration shown to Jews and Christians is not extended to other faiths (it would seem the Bahá'í get a particularly rough time of it).

But the comment I was replying to made a blanket statement that Islam calls for the slaughter and forced conversion of those of other religions, when the facts simply don't bear that out. Yes, some Muslim individuals and groups do hold to such an extreme interpretation of Islam; and media reports do suggest that most religiously inspired killings are committed by Muslims. But most Muslims don't hold such a stance, and most Muslim countries do allow at least some measure of religious toleration -- even a theocracy like Iran.

The most notable exception, of course, is the West's ally Saudi Arabia.

Take the data from the 2013 Pew poll, which theoretically represents about 1 billion muslims.

One of the questions was about support for the death penalty for apostasy. The report doesn't come with a global average, but you can go to the annex, add some census data and do the math yourself. You'll end up with a number of ~40%.

The idea that all muslims are out to kill infidels is of course ridiculous hyperbole. Nevertheless, I consider the number I just quoted worryingly high.

I agree with you.
