Ah. I had to re-read your post a couple times before I got your drift. I think you’re suggesting it would be fair to have sites critical of Catholicism or Islam come up early in search results. I suppose that’s so.
Actually, when I did the Google search on “catholic”, I noticed a set of links at the bottom of the page: “Searches related to: catholic” There I found “anti-catholic”.
I could not get an anti-TERM when I did the same search for Jew, Jewish, Islam, Islamic, Muslim, Christian.
Protestant yielded “Protestant vs. Catholic”
Huh. I wonder how they determine when to add “searches related to TERM” links.
