There has never been any belief in God litmus test in KTL, sorry. People who can make present their positions in a logical manner rooted in factual accuracy generally were well-respected and people who could not were not.
There were posters who believe in God who were well-respected there such as Brown Pride, Hellbound, Copper Scroll, and KingofSugaHill (he's an atheist now, but he believed in a higher power most of the time he posted). And likewise, there were posters who were atheists/agnostics/nonreligious who got shytted on because they spoke nonsense like Meta Reign, Gundamzeta, Newworldafro, and Hiphoplives4eva.
I don't want to kick dirt on Kev3m's name because this is his appreciation thread and obviously he's appreciated by a lot of people, but the notion that the reason he wasn't highly regarded in KTL was due to his belief in God, as opposed to many of the statements and opinions he presented is erroneous.
