No. You are making up a definition just like a Leftist would. An atheist is simply someone who does not believe in any gods. Just as you do not believe in Greek gods, Roman gods, Native American gods, or any gods of any other culture other than the Hebrew god, neither do atheists. They simply add the Hebrew god to the same list you don’t believe in.
I’m a Christian and agnostic on the existence of other “gods”. After all, our God is greater than all others because he is the creator. Being greater than something else actually requires that something else to exist. And the bible says it does in Psalm 82.
Well, you can decide that you THINK that, so that's what it means TO YOU, just as modern leftists have decided that Racism means "All white people's support of capitalism" instead of the traditional, sensible definition "disliking someone because of their race."
But the fact is, agnostic means without knowledge and atheist means without belief in gods. If your definition is gerrymandered so that you can define atheism out of existence, you are perhaps pleasing yourself, but I think most atheists will find they still exist and they still operate as they always have despite your views of them.
