The Forum is Biased for Atheism and Against Religion Yes, that was a statement on a position I hold in a thread on the topic; not unlike a statement by a theist on his or her own views on God, which would here be perfectly fine. It's also not a position I'm going around advocating for. I don't care enough to.
As for you own case, your threads were poorly composed. The thriving of religious discussion on this forum puts paid to any idea that there is some kind of editorial bias against it. You're confusing the moderation of your own poor posting with an editorial bias against religion. No doubt you'll see consipiracy here regardless. Everyone who gets modded tends to think it's a matter of philosophical principle, and not the fact that their posts are garbage. Funny that. But the proof is in the pudding, and the pudding is stuffed full of religious threads.
It's also ironic you're quoting Marcus on 'censorship', who was of the view that religious threads should be excluded from the forum on the grounds of not being philosophy - a sentiment which was roundly put down by all including the mods. That we've have two sides of the complaint within a week - on the one hand too much, on the other not enough religion - is something of a mark of pride for the forum I reckon.
