A lot of people think of religion as in your blood, like race. My sister knows that me and Ferrero left Islam (or at least I told her) but once when she was asking about Ferrero's background she still asked her "so are you Muslim?" I think she was trying to ask "so are you from a Muslim background?" Obviously most of us here would answer yes to the 2nd question but a definite NO to the 1st lol.
yeah i know i was having this argument too
religion is like a political affiliation, you leave it, and that's that.. its not a cultural thing, or an ethnicity etc
it would piss me off to call me a muslim now because my parents are muslims, or because i was a muslim, this is of course unless i tell you i'm not a muslim, i understand if somebody thinks i am a muslim because of how i look and my name etc
but if i tell them i'm not a muslim they should accept that, since its a religion and not my race
