I have a MySpace and a Facebook page, but I have found it's a bad idea to include my atheism on those pages, as it has a tendency to put you in a position of being pre-judged by new people you might meet. And while it's easy to say "I don't need them if they are going to judge me" the reality is, I'm a minority in this society, and also a pariah several times over. Being gay also, means that my odds of finding a partner are dismally low...I can't do things to undermine any success at it I might be able to have... if i ever hope to find new friends, have dates, or a partner, i first have to let them know ME without the trappings and banners of atheism, so that i can show them how their prejudices are baseless. But you can't go at it waving the Godless flag and expect everyone to accept you. This was also the problem with the gay community. They went about it the wrong way, for the most part. They behaved badly, and then expected people to treat them with respect. Bad behavior is bad behavior. But with atheism, it's more about the strength of religion in this country, and the brainwashing, and how people don't really know what they believe until they are forced to think about it. IF you try to force them to accept you as a nonbeliever, they will have a kneejerk reaction before they even give you a chance. I have numerous profiles on a plethora of dating/personal sites, and let me tell you, the minute i ticked the box for "atheist"--the silence was deafening. When i selected "other" or "not religious" things went back to normal.
I hate that this is so. But it is.
I am, at this late date, dealing with another round of prejudice in my life--and i feel safe saying that being an atheist is already much more difficult than being gay.
