Do some agnostics just not get it?

Yes, it very much is the case that a lot of people who call themselves agnostics don't know what the word even means (nor do they know what the word atheism means).

Claiming to be an agnostics and not an atheist is hardly what I'd call intellectually honest given that all rational agnostics are atheists (if you don't have any knowledge of whether or not there's a god then it's irrational to have belief in a god).

I suspect that much of the reason is due to cultural conditioning and the undue respect that religious nonsense is given in most cultures where the religious want people to think that the question of whether a god exists is somehow different to the question of whether fairies at the bottom of the garden exist.

Many religious people also believe that atheism is a belief in the non-existence of god instead of merely a lack of belief as an attempt to put atheism on a more level footing with their religion (instead of as the default in the absence of evidence which they can not provide). A lot of those who call themselves agnostics who claim it is some kind of third way between atheism and theism are probably using the definition of atheism preferred by the religious.

Places with high levels of anti-atheist bigotry can tend to be a bit less intolerant of those calling themselves agnostics than those who use the term atheist so atheists who live in those places would be likely to call themselves agnostics, many of them have probably only heard the religionists definitions.

I honestly think most of the sort of agnostic you describe are closeted atheists. They have the capacity to question their assumptions and view their beliefs critically, but are uncomfortable with the notion that there is no higher power guiding the Universe or fear persecution should they openly state their disbelief. In their position in the middle, they can sneer at theists, with their simplistic worldview and childlike credulity while simultaneously condemning atheists as arrogant, materialistic, and cynical in an effort to look better by comparison. They occupy the middle, not out of a genuine belief that the divine is unknowable, but because they are unwilling to make the final leap of of intellectual honesty.

I'm just going to re-iterate that this is only in reference to a certain kind of agnostic, not all agnostics.

I misread your post. Sorry, I didn't get enough sleep last night.

You are correct. Agnosticism is a state separate from atheism/theism.

Thats a personal question, you sound like the people your are describing in this moment.

We just recongnize those absurdities of religion without telling everybody that we know there is not the possibility of the existence of an almighty Being or force.

Telling that i just know i know nothing sounds offencive to you?

It is completely rational to say that you do not know a thing when in fact you do not.... I do believe you are allowing your emotional state on the subject to skew your perception.... on a subconscious level you appear to think we are somehow better than everyone else, we are not, only different

Because they don't know what agnosticism mean.

well as an agnostic, it's not that i don't believe there's a god, i do. just notthing any human can understand

No, they are learning which way to go; pro-faith or pro-fear.
