Most exmuslims don't leave to sin without guilt but do so after thoroughly researching Islam and its texts and realising there isn't a single good reason to be convinced Islam is true and realising Islam like all religions is childish fairy tales and mythology.
The amount exmuslims will drink, eat non-halal, have pre-marital sex vaires to different degrees. Many exmuslims don't like alcohol and pork and some are married. Many muslims drink and have marriage outside of sex as much if not more than exmuslims, with the thought process of “it doesn’t matter I sin, I can pray and ask for forgiveness, so it’s ok”.
Let me twit or tit this .."THE TRUE SHIT MUSLIM are those who says "Muslims left Islam because they want to drink, eat non-halal, have pre-marital sex yadi yada................."
