I don't. There is no point in explaining my point of view to a Christian, they will be unable to understand it. I steer clear of them typically, but if I do have to deal with one, I smile, nod, and leave as quickly as possible.

You don't. Just say no to their questions and kindly bow out of things. Your a unique person and its easy to be kind to people. Dont try to convince them that your way is the right way. Let them figure it out. Pressuring people is their way of getting what they feel you need. Think about how you finally changed and let them do the same.

I say religion is humankind's most destructive invention, and even if there's a god he wouldn't like religion.

i say i don't believe there's a god as we know ,or don't know it!

When I lived in Maine, it was pretty easy. But now that I live in Alabama, I avoid religious discussions at all costs.

I don't, I just don't think it's worth the aggravation..

I just walk past them and ignore them, just because I don't believe ion their god, doesn't mean I have to rub it in their faces.

Why would you even bother? I'm as bothered by that as I am someone telling me that they are a Christian, who cares??!!
What you believe, or disbelieve is about as personal as your sexual preferences. ONLY appropriate in the proper CONTEXT.
That's what's so the matter with us as a species. I'm an atheist...yea me! I'm a Christian...yea me!!
NOBODY CARES......
Remember what your mother told you.... It's impolite to discuss Politics, Sex or Religion

I live in Islamic county and telling religious people my real believe is not a good idea

Is not a problem to tell them in what you trust ,the complications start when after the question "Why you don't trust in god(the religious one),in jesus etc?"Then you start to explain what you think about their religion and they look to you as an enemy .....Part of the show for me )))

I usually keep it to myself. Eventually they get the picture and either keep me as a friend- however misguided, or shun me. If they do ask me outright I answer honestly by saying: "I believe in science, reality and having fun!"

Australia, where I live, is supposed to be a christian country too, and like the U.S. different states are more so than others. I am up front with people about the fact that I am an atheist, and if they want to know then I tell them why.
I tell them I have studied theology at university level, as a committed christian, and came away realising that it is based on MYTH at best, and at worst it is simply outright creative fabrication for political gain!!

Generally I find people tend to keep their religious orientation to themselves. Therefore I'll only reveal my atheism on a case by case , need to know basis.Sometimes I feel comfortable to reveal my beliefs and other times it feels more appropriate to keep them to myself.

The subject rarely comes up, but I generally just tell them flat out. Which inevitable leads to, "I'll pray for you." I always reply, "I'll write a letter to Santa for you." They tend to shut up.

You don’t really need to tell them . I’ve worked very diligently at being able to talk to people without that being a issue. I’ve learned to focus more on them when discussions of that nature come up. When proclaim this, or that all we do is help promote division , this makes it difficult to communicate. I put humanist in my profile because something had to be there .

I'm blunt and tell them right away. I don't BS about it. My whole work and family know. Respect the believer, NOT the belief. I learned that.

Don't. Not worth the drama. My motto, live and let live.

Did tell my sisterthat, if I'm going to christian hell, i'll have plenty of Christian company. That usually ends her judgement.

I think it's irrelevant. If they don't ask, I don't tell.

Definitely, tell them. Spread it as far and wide as you can. Who knows? Maybe they will come out as an atheist as well.

I always tell so they know not to bother me with religious doctrine. If they don't want you around anymore they are not worth your time. Telling you are not a believer can actually get a lot off pressure off you. You don't have to feel uncomfortable anymore when certain topics come up. You can give your opinion freely.

I slam their religion without mercy and give examples of why their respective religion is crap.

I don't really have a problem telling them , sometimes it can lead on to some very interesting conversations.

Inspired them through the ideas put forward in the discussions

I live in the bible belt, and for the longest time have hidden my atheism, when people start talking about Jesus.
I still keep my mouth shut, unless directly asked. "You believe in Jesus, right?" "--No. I'm an atheist."
I don't get asked much, so I don't have to out myself much. Most Christians assume that everyone agrees with them, and most of the time they don't expect, or want confrontation any more than I do.
