There is no compulsion in religion (Qur'an 2:256), but to use the old Clinton Qualifier, that depends on your definition of compulsion. Islam itself is contradictory on this point, as Islamic law is rife with various forms of subtle and not-so-subtle coercion to submit, up to and including the choices afforded to unbelievers by Qur'an 9:29: conversion, subjugation, or war. But hey, no compulsion or anything. Just an offer you can't refuse if life can be made sufficiently uncomfortable, humiliating, or dangerous for your intransigence. That is the situation in which this community finds itself. "Conversions threaten Pakistans 'Macedonian' tribe," from Dawn, October 20 See also: Afghanistan's Nuristan, formerly Kafiristan. But no death penalty, apparently, as a convert to Islam who changes his mind would face. http://www.dawn.com/2011/10/20/conversions-threaten-pakistans-“macedonian”-tribe.html
