It's asinine to call yourself an ex for something you never labelled/identified yourself with at least some illusion of minimal level of choice....I am ex muslim the same way I am an "ex- child" or a "ex-school attendee"
Fair enough some people here fell for the bullshit for a period & practised it, but many on here were only muslims cos their parents called them that...
I'd definitely consider myself an ex-Muslim. Sure, I was born into it and did what my parents taught me, but when I entered my teen years I really thought about it for myself and felt an unwavering oneness with Allah.
Hell, early in my first year of college, a (non-Muslim) friend and I got into the topic of religion. I still remember her asking me about my faith, and I got this real serious look in my eye and said with utmost conviction that I'd already been through the questioning phase and that my faith had come out much stronger for it. Man, I was an idiot
Less than a year later I found myself on the path to atheism and apostasy (thank the lord for that!). So, yeah, in my case there was definitely a phase of my life in which I made a conscious choice to believe.
