Earlier quoted context omitted.
In that quote, Wallace is just morphing, conflating, and fudging the definition of the word "worship". He says people "worship" (with a variety of subtly different meanings) a variety of things and then, implies that because we can use the same word, "worship", to describe those activities, they are equivalent. I despise this rhetorical technique. I find it both insulting, intellectually dishonest and useless.
It is not logically rigorous, but it illustrates a point. Can you expand on why the distinction you are drawing is important?
The point he has relies on a faulty premise. When people talk about religion and atheism, they aren't using the definition of Wallace. They're using the strict definition - non-theist. Not a theist. They don't believe in god. they are saying absolutely nothing about the rest of their philosophy.
He RELIES on changing the definition of religion into something it very clearly isn't. And he does this in order to provide evidence that people, who obviously exist, must not according to his definition. It's like saying "Homosexuality doesn't exist, because all homosexuality is is is rejecting the beauty of certain genders. But we all recognize the beauty of our mothers and brothers and fellow humans, and the grace they give and the home they provide. No human would be human without loving thy neighbor".
It's insulting. And other than that, it has absolutely no value, intellectually, morally, or otherwise.
