Read this post from the blog of the religion reporter at our local newspaper.
My comment was long, so I wasn't sure if it got posted and thought I'd post it here, as well.
Three comments, in mixed order:
First, the study isn't worth the attention it's getting. In addition to all of the other problems with IQ, the variance here simply isn't notable. This is a weak correlation and little more.
Second, the UTSA event is not to everyone's taste, but your question; "why equate it with pornography?" is an interesting one. The implication is that you'd like to label porn as 'bad' but the Bible as 'good' or 'not as bad'. I don't find pornography objectionable, yet I find the Bible incredibly objectionable...so, your implication is correct, they're not equal. I think most Bible-supporters know this which is why, despite calling it the "Good Book" not one of them would agree to let me read Bible stories of my selection to their children.
Some people are uncomfortable about nudity and sex, and that's their prerogative.
Those, though, who would exalt a book that explicitly endorses slavery - the owning of another human as property, the beating of that property and the instruction for slave to obey cruel masters - just one of many objectionable points, can never claim the moral high ground. They have sacrificed their humanity for a poisonous and corrupt ideology.
And that, leads me to the third point - the focus on the fact that this individual had books on atheism and demons. There is nothing within atheism (because it's a single position on a single question) that would direct one to burn a church. Atheism is not a necessary and sufficient cause for any act, let alone this one.
But the problem here is the self-righteous bigotry in both the headlines, the focus and the commentary. Where is the headline that reads "Bible found among clinic bombers belongings"?
