AOL's Covert Anti-Christian Crusade?

Why is it that the AOL-owned and operated Beliefs & Religion - ICQ Chat Rooms include Atheism, Buddhism, Hinduism, Islam, and Judaism, but not Christianity? Is AOL just discriminating against religions that don’t end with “m” or is it something a bit deeper? Personally, I don’t care too much for any of the world’s famously fragmented violence and hate-breeding schizophrenic schism-isms, but if AOL is going to sponsor such an area it seems that it should be open to ALL or not open at all.
