actually what you call agnostic atheism is what i understand it as simply classified as 'no belief'.
and you're correct that not all athiests have an above average grasp of scientific concepts, most of them actually belong in 'no belief' but atheism has become some sort of fad as recent.
i remain a dedicated moderate agnostic
"No belief" or "non-belief" is an incorrect term in most cases as it does not specify what the lack of belief is in reference to, which could lead to confusion. Atheism is specific towards a lack of belief in gods/deities, and therefore is more appropriate.
And I don't see why atheism is a "fad".
Personally, I feel agnosticism would be more appropriately described as a fad, rather than atheism. Even though I am agnostic atheist, people tend to misapply the term "agnosticism" and use it to disguise their own subtle leans towards theism.
An agnostic was originally defined as someone who denies claims to ultimate knowledge (e.g. they would deny someone's claims if they claimed "god exists" or "god doesn't exist" as that employs absolutes and implies that the speaker knows that god does/doesn't exist - even though that is impossible).
Thus agnosticism as a position on knowledge is compatible with atheism or theism, which are positions on belief.
However, many people now seem to apply agnosticism to describe how they are "unsure" on issues of religion or spirituality, or to proclaim that "we can't know for sure if god exists or doesn't exist, so I am agnostic".
There is no problem with the above. Definitions change, words take on new meanings. But I feel it is a fad when people only describe themselves as "agnostic" without even attempting to describe their viewpoint on either atheism/theism. Or even being pretentious enough to criticise both theists and atheists.
Really, why is it that gods/deities seem to be the only concept that affords the prestige of having people say "I don't believe, but I don't lack belief either - I am agnostic". Why aren't people "agnostic" about unicorns, or ghosts?
Note: philphie, this isn't directed at you, but more towards some other agnostics I have encountered in my life.
