Well, because there'd be no article left once I removed all the superfluous psychoanalysis.
Then we will see how many agree with your point of view.
Let me be clear. There are two ideas we're dealing with here. One is the objection to atheists' attempts to remove religion from the public sphere. On that score, the author and I are likely in considerable agreement.
The other idea is the author's attempt to explain why atheists act as they do, and what they should believe if they really were atheists. It is that idea, which pervades this entire article, that I have a beef with. When non-Christians do the same, and try to tell me what I'm supposed to believe as a Christian, it's frankly off-putting and usually incorrect. When someone tells me I "hate gays" because I happen to believe all extra-marital sexual activity is sin, they're wrong. Well, it cuts the other way, too.
Again, just because we're on the same side doesn't mean that ever argument made on our side is a good one.
I'd be willing to bet there would be at least one person who would say, "what a dumb article".
Fine with me. That's the chance one takes when one puts their writing out in public.
