I agree with others, its extremely sad that there isn't more respect from both sides. I have witnessed atheist friends being hassled in the street by people spouting fire and brimstone, and I have experienced some very nasty workplace harassment when the HR officer decided, breaking confidentiality, to tell my junior staff that I am Christian.
I'm a scientist, I also have my faith. Its very sad that some people are so narrow minded that they lose respect for someone simply because of what they believe, that they find people with faith "ridiculous".
I also think its sad that religious people seem to be fair game for all number of insults, slurs and mass judgements. Its a pretty shitty thing to do to, and to use the "well what about all the bible bashers who rant at me that I'm going to hell?" is a rubbish justification for ranting at someone and/or being verbally abusive.
You often won't know why a person really chooses to have faith, those reasons can be deeply personal and rooted in trauma - my own reasons for believing are. Why not live and let live? Why are there so many people who feel the need to try and convince others that their beliefs (religious or otherwise) are the right ones?
There aren't many people in RL who know I'm religious, I don't advertise the fact as I don't think its relevant, much the same as I don't advertise the fact I'm vegetarian - my beliefs are personal to me and unless they become relevant I won't mention them. We're also not raising DS to be religious (DH is an atheist), when he's older if he asks I will tell him I believe in God, but helping him to find his own path is very important. I was raised strictly atheist and decided to follow religion as an adult.
I think YABU OP, we all have views and beliefs unique to us as individuals, why does it matter what someone's beliefs are,with the obvious disclaimer of so long as they aren't hurting anyone.
