The site is WAY TOO bland for a subject that is very rich in controversey, opinion, discussion, views, and general philosophical thought. I know your site is neutral in terms of taking your own side with religion, but you need to jazz the site up a lot. You need color, period. Perhaps include images on each religion category page that reflect that religion or the country that the religion is practiced in/founded in. This is a rich subject; it lends itself to infinite opinion and discussion not to mention an overall learning experience for those interested in other cultures. Reflect that in your site design, including your title/logo. The structure seems fine for the amount of info and links that you need in the site.
