"Atheism is a religion"
Yes, just like how not smoking is an addiction.
Hardcore believer who will ram their opinion down your throat, tells everyone they're stupid for taking as truth their beliefs, and in general being a rabid fundamentalist who no-one likes.
Now, did I just describe a follower of a religion or a follower of a non-religion?
Alternatively, think of it as love, hate and apathy. Religion, atheism, agnostic. There are two opposites and one neutral, and from in the subjective opinions of a fair few people, religious and atheist are flip sides of the same coin. Both decide the other has no place in this world, both will attempt to undermine the others belief system at any opportunity, and they're generally rabid nutcases. While agnostics are the fence sitters who profess belief towards neither, leaving their options open as it were. That sort of mindset will usually (in my subjective experience) lead to a more inquisitive mindset. Great for group research assignments.
In the case of smoking... I smoke and you should too, I don't smoke and you should do the same, I don't see the need to inflict my opinion on either of you. Or I Don't Smoke, all uppercase. Think of it as a non-smoker as opposed to a Senator whose campaign involves campaigning against smoking at all possible times. Not all non-smokers/atheists are like that of course, but enough are so as to give the general population a decidedly dim view. Alternatively, just think of it as any time a system of thought has people trying to convert others to their point of view, it's a religion. Unless you're thinking purely in forms of technicalities in which case no deity and obviously it's not a religion. Like Voodoo, and Scientology.
