Let's face it, Islam is a very Arab-centric religion. The Arab customs, habits, food, clothes and of course language of the Arabs has been raised to Divine status as a result of Islam.
How did (does) that make you feel?
Did it play a part in you leaving Islam?
I personally hated the hierarchy amongst Muslims that always placed the Arabs at the top in whatever meeting or gathering one was at - and I am part Arab!
I also didn't like the way that so many Asians tried to be "Arab" - it seemed demeaning to them and it didn't seem right.
And let's face it - if you don't understand Arabic - you will never be able to win an argument with an Arab. ("Oh you don't understand the TRUE meaning of what God says - coz you don't understand Arabic")
It is always assumed that any truly pious Muslim must try and learn Arabic.
God is so parochial!
I would not say it played a role in why i left Islam.
But i have noticed when i was a Muslim, i was disliked by the Arabs because i was African.
We do tend to be looked down on both the Asians and Arab community as lesser Muslims than them.
Arabs i have ran across has expressed they are more Muslim because Porphet Mohammed was a Arab and he had slaves and therefore we were filth and below them, infact i recall my uncle going Mecca. He got searched so many times just because he was Black.
Even White converts are treated better than African Muslims imo.
