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.
