most Christians and Buddhists that I know understand the role of religion (and when to NOT use religion).
Not so for the Muslims.
And how many Muslims do you know? Most Muslims also know when NOT to use religion. There are more than a billion of them - if half a billion of them did not know when to use it, I think we might have a tad bigger problem that we currently do.
Remember, the kooks you see on TV are like the kooks you see for other religions as well - they are the minority. Hell, the way faith is involved in politics in the US and informs policy decision (veiled as some other excuse) has done far more harm to the LGBT community than most other religions.
For me, religion is a social need, that brings peoples who think alike together. For example, change cities because of job and want to make friends, go to your friendly church (or bar). Need to really meet people that share your values, join their club.
As for religion, in times of stress, there is nothing better. I happen to be a doubter, but when I am stressed, I join my community for a while. Do I believe in all the ritual and fairy tails, and the "he said" that was documented 400 years after the fact? You have one guess.
