You should have had a lot of guts to convert out of a religion that threatens so much with hell/death for anybody who doesn't be in it. Anyway, I still didn't get the answer to my original question, what are the kinds of challenges a muslim faces if he wants to convert out of it?
According to quran, I read, he is sentenced death. And I also read many former muslims in the west keep a very low profile to escape that sentence and converts in Islamic countries don't even reveal it to anybody. But what is the ground reality? Is it really that dangerous? How do family/friends take it, etc? I am sorry, if I am asking an inappropriate question and please ignore me in that case.
