This is not a thread about race. I'm going to use race as an analogy to make a point. I'm also going to use a censored form of a racial slur to make the point more strongly, namely n***er.
I would not use this term except in fiction or a thought experiment like this.
It is the position of Godlessness, that there is no God or that God should be opposed and rejected, then turned into a DOCTRINE or TEACHING.
ATHE-ISM is the "THE TEACHING OF GODLESSNESS," the doctrine that there is no God.
"Look at the WORD," they say, "It is just the negation of wifeism! A-wifeism! It's clear!"
So again is it with "atheism", which is a TEACHING of the DOCRINE of GODLESSNESS.
But this is simply false. "All atheists are non-believers on God" is true, but not "all non-believers in God are atheists."
To be an "awifeist" is to TEACH the DOCTRINE of BEING WITHOUT A WIFE.
To be an "atheist" is to TEACH the DOCTRINE of BEING WITHOUT GOD.
1 Not how "atheism" was coined
2 Not how it is used by academics
3 Not how it is used in ordinary language (87% of English speakers use "atheism" to mean "believing there is no God.")
4 Not how it is historically used
If you want to expand your numbers, you can always attempt to claim "without X" equates to "a specific doctrine in opposition to X."
If YOU are not a fascist, that doesn't make YOU a member of Antifa.
Atheism goes well beyond a mere "lack of belief" in God. It is an active, oppositional rejecting disbelief in God. The intellectual conviction is secondary at most to the willful conviction.
