C'mon people let's not argue which religion has contributed more to Britain, that's not what the OP's original question is. Im sure different religions have contributed in different aspects.
Well to be honest, when I first came on TSR, there were dozens of anti-islamic threads daily (It has improved a bit now), I would usually post on these threads and end up losing my temper, I just ended up getting neg rep's and warning levels. Looking back at it, there was no point in this, people can think what they want about Islam, at the end of the day I am what I am today, because of my religion. I have friends from all religions and backgrounds, and they respect me and my religion, TSR does not account for the whole population, not even 1% of britains population, not everyone is the same.
