I find some Athiests unknowingly behave a lot like a members of a fledging religon.
The worst of them go out of their way to desecrate other religions as often as possible, hold that their way is superior to all others, do their utmost to recruit as many people as possible to their way of thinking, and if you don't wholeheartedly and immediately agree with them on it, they cry persecution
Just saying....
Also where im from people tend to keep their religion to themselves. Its generally bad manners to bring religion into a conversation, and the only people who constantly break this social taboo here are athiests, making shit of everyones religion when the taboo exists primarily to ensure people don't get offended, or that their beliefs aren't trampled on.
You can be an Athiest, Catholic, Protestant, Baptist etc. etc. as much as you want as long as its in your own time and you don't bother anyone else with it. However thats here.
From what i've read in this thread Americans seem to be plagued by on the street preachers, because of the 'Religion is your own goddamn business' taboo here we tend not to have many of them, and its seems much more prevelant in American society, we don't have a 'bible belt' part of the country So i can understand the exasperation by some American Athiests on here, ye have to battle for your right to be an athiest, but back home some of our athiests quite frankly are just viewed as bad mannered people. My beliefs regardless of whether they are Catholic, Protestant, Athiest, agnostic or otherwise are no one else's business. Its not about whether you believe or what you believe or whether you believe at all, its about respect for other people.
*edit* realised i strayed off point. I don't think athiests are as abundant online as we think, Just depends where you go or what sites you visit. The escapist demographic for example would be largely teens to twenty somethings. If this site a had a demographic of 40 to 60's there would be more religious people apparant i'd say.
