Religion discussions are generally boring, MOS.
I'll see your "Religion discussions are generally boring, MOS." and I'll raise you a 44-page religion thread on the G&O.

I think it's simple. As it pertains to the religion board people see it and think "meh".....they never even click the board.
But a religion thread on the G&O! Oh boy!!

That's potential entertainment gold!! The "LOL" possibilities are almost endless. On the G&O, religion threads (99% of which are attack ridicule threads) can get traction via bandwagoning against theists, random meme posting, hit and run attacks, virtual high fives with like minded unbelievers....ample ridicule and mockery potential galore!!
That's why most theists stay away and don't comment in the threads.
That's also why God haters like Croatch never actually deep dive in the religious discussion....just hit and run attacks and when called on it gives the coward's excuse "religion is illogical and stupid and beneath me....not worth my time" spiel. LOL, ok.

On the the religion board I'm a moderator and can actually moderate the religion threads. Too much on the G&O for mods to constantly babysit a few religion threads...I get it.
