Oh sure it is, for some people. I see it on here all the time. Any pro-religious post or thread immediately gets it's share of "I'm an atheist! Everyone acknowledge my atheism, now!" responses.
That isn't practicing atheism, that is practicing being a jerk. That behaviour is neither implicit nor exclusive to atheism (especially when you remember that the
vast majority of atheists never even talk about it). That'd be like saying that terrorism is practicing theism because some terrorists should about their religion when they're doing it.
Well, actually atheism describes an antithetical philosophical position. Not a person. The "atheist" is just what we call a person that subscribes or claimes to subscribe to that antithetical philosophical position.
You keep complaining that other people refuse to accept your definitions yet you continue to blindly ignore any other possibilities. That might be how
you use the word but it is demonstratedly not how many other people use it. Even if you don't accept the semantic validity of their definitions, you have to recognise that when they use the term, especially about themselves, that is what they mean.
If someone calls themselves atheist, you can't just declare that they hold that "antithetical philosophical position" when they say (or even demonstrate) that they don't. You can say they don't fit your definition of atheist but that is all. And in general terms, you can't declare that all of the people identified as atheist (by themselves or others) automatically meet your definition.
Why are they a "subset" in your mind?
Subset doesn't imply a negative, it just means a part of the whole. My point is that they don't represent a majority of people who don't believe in any gods and therefore you need to be careful using their behaviour to judge all people who don't believe in any gods.
I am a theist by choice, not by knowledge or belief.
That is a strange concept to me. What reason would there be other than knowledge or belief?
I use the upper case to designate the meta-concept of God, as opposed to any specific religious god-concept. "God" as the English term referring to the great mystery source, sustenance, and purpose of all that is.
Interesting, it's almost as if the same word can have different meanings in different contexts isn't is?
Whatever God is, or isn't, it's by definition far beyond our comprehension.
If you don't know what God is, how can you
know it is beyond our comprehension (especially since you've already claimed your theism isn't based on knowledge)?
"God" is written into our DNA.
I wouldn't say it is directly genetic but humans have certainly developed to have a desire (maybe even a need) to have some kind of explanation for all the things we don't understand, largely because we evolved a creative imagination and so have a fear of the unknown. That doesn't mean any of the things we imagine (individually or collectively) to explain those unknowns are actually real (either the gods or all the other things - fairies, ghosts, aliens etc.).
You can reject it if you want to, but as there is no reason for doing so, and there are some good reasons for NOT doing so, rejecting the possibiities seems foolish, to me. But you do you, as they say.
I'm not rejecting the
possibility though. Your definition of atheist means someone who rejects the possibility but that is not the definition most people use and certainly not the one I'd use. Again, you can argue about the validity of the labels (which is why I generally don't use them in the first place) but you can't argue that I believe something I don't.
