Hi this is my first comment on this site. Im an ex-muslim. i embraced islam while at teenage. left (first time) after around early 20s. on/off for few years due to confusion/whim and fear of threats and advice of "false hope" from other muslims. left permanently not long ago.
you know u're an ex muslim when from my experience
1. you do not have "fear" of "allah" whatsoever although u might fear threats from muslims but its natural fear, unlike imaginary "fear" of "allah"
2. you are happy not doing anything islam "command" you to do so
3. you do not feel guilty in doing most "haraam" that islam "command" you not to do so. i said most cos some others are naturally wrong, like be rude to ur parents , steal and other few things, your own basic common senses you even see in law in the west. so what i meant is nonsense "haraam" that islam made up the like of being non muslim, drinking alcohol, smoking, sex outside marriage, wear short above knee, and so on.
4. you hate muslims cos they r ones who follows a man who married 6 or 9 year old girl, the one who killed a woman himself, the one who ordered apostates to be killed and yet they all condones that. there r many more sick things they condones and you hate them for that.
5. you hate the victorious of islam. cos you sense arrogance, oppressive, intolerance, violence and murders they desire to bring upon those who opposes in this world.
peace and no not peace be upon you. if you speak like muslim yet you do not believe in heart, then know you're hypocrite, beware.
