I am the only "religious" person in my family, and pretty much all, 100%, of my real-life friends are agnostics or atheists (some very militant). Many of my students and also some colleagues at work (at my university) are Heterodox Christians, mostly Baptists, but there is no friendship between me and them. The only people who are devout Orthodox with whom I communicate are the people on this Web site, and also a handful of my co-parishioners (but I only see them and talk with some of them once a month, at best - sometimes even less often...). So, I know the feeling of being very, very alone as far as faith goes. It can be excruciating, it can really drive you nuts... but we have to endure!!!
Now, I am blessed in that my wife, an agnostic, does not really attack or bash my faith. At least she does it only occasionally. Moreover, she goes to Divine Liturgies with me, because, as she says, she knows it's good for me. Also, my friends who know that I am Orthodox do not usually attack or bash Christianity or the Orthodox faith when I talk with them or when I am present in the room. They just avoid the topic, tending to move on, to change the subject when I say something about Orthodoxy (and then, when they leave, my wife screams at me that I AGAIN EMBARASSED her and that when, for Christ's sake, will I mature and stop this idiotic childish religious superstitious mumbo jumbo talk
). Some of my old friends with whom I used to be close in real life, and now am friends on Facebook, say, every now and then, things that hurt me; for example, a while ago I asked on FB, are people bothered by my posts where I talk about Orthodox saints and feasts, and some of those whom I consider real good friends said, "no, they do not bother me because I just hide them at once."
Perhaps the most painful thing in this whole story is that my daughter, who will be 26 this coming July, is growing more, and more, and more hostile to religion, becoming a progressively militant atheist. Her husband seems to direct her in this evolution, to be her role model. Her husbands' parents and their whole huge extended family also supports in her this feeling of bitter animosity against religion. Within the last ~2 years that she has been married, I learned not to raise, even remotedly, any subject that has anything to do with Christianity, Orthodoxy, because I know that if I do that, there will be tension and possibly hysterics. I does not get any better, only worse, and worse, and worse. And I can't begin to tell anyone how much I would love to see that changed - and I have no idea how it can be changed.
But again... we have to endure. Running away, severing ties with the people you have befriended and whom you love, changing jobs, addresses, locations - well, I doubt, honestly, that any of that can help. Just endurance...
