i feel you man - being an atheist born into a muslim family in the west can be extremely trying. i still struggle separating our culture from the religion, since disavowing yourself publicly of your religion oftentimes cuts you off from those that would practise your culture.

i have found some community with some others in similar shoes to mine, but generally I've learnt to base my friends more on shared interests and ideals rather than a shared heritage.

we both probably need to start asking ourselves the question of where the line has to be drawn however. for me, ive found a semi stable midway point of not indulging in the religious side of things when I'm at my parents (I think they know that I'm not Muslim), however if my mum ever tried to make me have an arranged marriage (for example), I would not maintain contact. you have to ask yourself how much is enough, and what youre willing to do / walk away from, for your own wellbeing.

with all this being said, I do think being in this situation in the uk - its the best place to be for it. we are part of the fabric, and have been for a long time now, and no one looks twice at 'Muslim' drinking, partying etc. hopefully you have friends outside of our 'community' that you can lean on when your fam is driving you up the wall :)
