There is a saying that "Religion is the opium of the people". There are even less gracious opinions that suggest most, if not all, religions are means of controlling people, or at the very least, a technique to make people "belong" to some group or other.
Having said that, there's another view that states "Race and Religion are the two most divisive things in the world". (Apart from issues of poverty and money, of course).
I "converted" to Islam a couple of years ago, not for religious reasons, just expediency. I consider that I was a Moslem for about 90 minutes before I saw the error of my ways and went racing back to being an "infidel" again.
Indonesia is trying to get to grips with the notion of "democracy", but the government here still orders us to belong to one of the "approved"/"sanctioned" religions. That makes little sense to me, but then, I come from a different world. Spiritual dogmas have never worked anywhere, and most likely, never will. And personally, I abhor notions that supreme beings tell a few mere mortals what they're supposed to do in life.
Mass killings of people, historically, in the name of one religion or another, seem utterly ridiculous to me. I used to know an "educated" western psychologist who was a Baptist and he really believed (probably still does), that black people don't go to "heaven".
The less that people have to do with organising, controlling and making money from "religion", the better. I refuse to be part of any contrived system of belief that has the audacity to tell me how to live the life that god gave me. Whether I can use a condom, play music or eat pork, for examples.
Certainly, we all have to live somewhere and pay due respect to the feelings (and beliefs) of the people around us. That doesn't mean we have to believe everything we're told (especially deep down in our hearts).
An ancient Arabian (?) poet\philospher once said:
"...with their teeth half-shown in causeless laughter
and their efforts at talking so sweetly uncertain...
when a child sits on his lap
a man is blessed
even by the dirt of their bodies..."
Sounds good enough for me.
I think the author was one Kali Dasa...
