"The penalty for falling away from the faith of Islam after you have converted, is (of course) death."
"of course" ?

"There are 1.4 billion Muslims who live in more than 140 countries. They constitute the great majority in 53 countries that declare themselves to be Muslim states. Most of these states have constitutions that guarantee freedom of religion, as does the Afghani constitution. Most of these states have criminal codes that do not include apostasy as a crime. Among them are: Algeria, Egypt, Indonesia, Iraq, Jordan, Lebanon, Malaysia, Morocco, Syria, Tunisia and Turkey.
Other Muslim countries, however, criminalize apostasy on the basis of doctrinal constructs established in the 7th and 8th Centuries, which have been mildly questioned over the years or simply sidestepped. States that recognize it as a crime punishable by death include Iran, Nigeria, Pakistan, Saudi Arabia and Sudan. However, there are no known cases in recent times in which someone charged with apostasy in these countries has been put to death."
" However, there are no known cases in recent times in which someone charged with apostasy in these countries has been put to death."
I am assuming that the type of muslim fascists who would force a conversion at gunpoint would also be the type of muslim fascists who would declare a fatwa on someone for apostasy.
