And when you use it in the latter manner you use the term incorrectly.
No. I'm sorry, but common usage includes both uses. In philosophy both uses are used - and here we are in a Philosophy subforum. Just what group do you represent and why do you think they have the patent on the word? Are you the Minister of Language?
here's what the Oxford English Dictionary says:
Atheist:
One who
denies or disbelieves the existence of God
It then goes one to cite usage going back to 1568.
Atheism:
Disbelief in, or
denial of, the existence of God.
Citing usage going back to 1587.
(my emphasis added.)
Is there some reason why I should believe your definition of the word over that of the full edition OED, common usage and the usage of philosophers?
Where do you keep coming off acting like you are the arbiter of this word's usage?
Atheism is simply a lack of belief in god, and no more.
Again, that is the way you use the term. Obviously you do not remotely have consensus. And the average person - ie. English speakers who determine via use the meaning of words - and philosophers use the word to include your definition AND the other one. I could see if the word was a technical one used by botanists, or some other expert group who disagreed with general usage, but in fact the experts will agree with general usage: ie. philosophers and theologians agree with general usage.
Generally, the word is used incorrectly. So what. I'm correcting that, as are many other atheists.
No, you are advocating a restricted use of the term as if you and these specific other atheists are the arbiters of the English language.
What 'both kinds'? Atheism is simply the lack of faith in god. There are not two kinds. The diversion happened fairly recently when fundies started accusing atheism of being a belief proposition, and people have fallen for fundie rhetoric.
No, it is not recent.
Opposite to, not 'opposed', like the antipodes are not against the podes, for instance, but opposite to. Anti-inflammatories reduce inflammation, they do not demonstrate against it. You have to separate the idea ideas from the people that hold them, something electrafixtion struggles with too it seems.
Condescension will get you nowhere if your arguments are weak.
Anti- in antiimflammatories can be taken to mean reduce or 'work against'.
Are you saying that anti-theism reduce theism or theism?
That is a strange concept. Again, exactly as I said above, this would imply certain kinds of action that the strong theists I know do not engage in. They do not set out to reduce theism. That term would be misleading.
But you could try to convince relevent experts and the general public to use your terminology. So far you have not or have not been convincing enough and both groups continue to use atheism to mean both those who lack a belief in God and those who believe there is not God.
I never said anything about demonstrations.
