A small group of loud atheists live it as it was a religion
And the rest of the atheists live it as part of the general religion of their lives.
Not really. You use the word religion in a way that is not acceptable by the rest of the world. All of the definitions of religion which I could find include a belief or faith in a god or the supernatural.
You've made up your own meaning for religion, which is simply "Anything on which you spend a lot of energy". This means everyone posting here has multiple religions - any hobby you have (such as correcting logical fallacies posted by forum members) becomes a religion to you.
By your own definition, you simply posting here regularly is a religion - you have at least two religions, maybe more.
That's the way we are, isn't it. If you picked up one of the original printings of the Bible by the King James crew, you wouldn't be able to read it except that you had special training. And, the funny thing about it, it is English.
As far as how I use the word "religion," there are many in the world who understand it that way.
As far as making up my own meaning for the word "religion," my restating of the definition using other words than the dictionary I quoted previously, is a thing that kids are taught in schools all over. They are taught to say "it" in their own words. The idea is to get an understanding of something by the words used.
In the definition of "religion" found at http://dictionary.reference.com/browse/religion?s=t, definition number 6 states:
Quote
6. something one believes in and follows devotedly; a point or matter of ethics or conscience:
to make a religion of fighting prejudice.
to make a religion of fighting prejudice.
While this definition is most certainly not the popular one, it is still part of the meaning of the word "religion."
As far as I, myself, having more than one religion, perhaps it is not incorrect to suggest this. But, maybe it is all part of my personal religion. How many religions do you have?
Part of a meaning is not the entire meaning. Unless there's a god or supernatural beliefs involved, your definition of religion is only part the usual definitions of religion. Therefore you aren't using the word the way it is usually defined.
