Why isn't rationality everything? (in relation to using rationality as a means to refute religion)
That is what atheism means. Its not because I say so, but because that is what the word was created to mean.
An atheist that thinks being an atheist means something else such as that you hate religion or do not believe in anything supernatural is confused. Hating religion is anti-theist.
Likewise, an agnostic who thinks they are not an atheist is confused. They lack belief in god(s), thats all atheism is.
Theism = from the greek “theos”, meaning “god”.
Atheism = from the greek “a” meaning “without” and “theos” meaning “god”.
Then in classic philosophy the word was parsed into “weak” and “strong” (and eventually even more uses) in the formulation of specific philisophical arguments, which is what S is trying to explain to you.
Then, anti-theists who were ignorant of what atheism meant but had heard theists use it as a negation or opposite of religion (and as a word encompassing immorality or certain beliefs about religion) began using it in an equally confused manner to refer to themselves.
It has become a misused label in social movements, but these are bastardised uses that added meanings to the word to service an agenda.
