I think most people that are faced with a huge number of theists in their social circles know this one.
Let's hypothesize that you are with your friends. Worst case, they are all strong believers. In that case you try to avoid talking about your non-beliefs because that would cause them to ignore you and marginalize you.
I have a strong fundamentalist friend that I know him since 1'st grade. We were best friends ever since. His parents are the aggressive and strict type ( they do not even have internet, or TV ). One day I told him about my belief and his sister called me an idiot and retracted like I was suffering from a contagious disease. My best friend was noticeably disappointed. It all happened when I was at his home, without his parents ( which, by the way, are good persons just deluded; shame ). In the end we had a constructive conversation, I trying to express my opinion, he trying to 'lead me to the right path'.
I wasn't as informed as today, but I managed to support my views and in the end I saw that specific doubt in his eyes, but that was just a glitter. In his case, leaving his belief would have devastating consequences. I didn't want to proselytize. We talked and then we parted.
Over a longer period of time, we saw each other increasingly rarer. When I was returning home from somewhere I stumbled upon his parents. I have greeted them. They greeted me. Then we parted. They were very lively persons, and talkative. Those were clearly other eyes with which they looked at me. My friend adopted a variation of that cautious look, the look USA would give to Russia or China. We were rivals. I am sure the new of my atheism propagated inside their "box", scaring everybody on the way: "Look, even Johnny embraced this demonic occidental view of the world. The end is coming. Be strong, my brothers!". I was mostly excluded in time from their social circle gradually. I do not meet the given requirements. I am a minority, and bigotry is strong.
This is one story, but I have numerous encounters with every person I talk to about this matters.
Social punishment is a consequence that every minority faces. When you add ignorance, fear, bigotry and, mostly, superstition, you get a unstable and explosive mixture. All this is not necessary. I hope our children are going to live in a better world, not dominated by unjustified and superstitious beliefs.
I lost a friend.
