To make a long story short, Stack Exchange is rolling out a new Code of Conduct and enforcing it on moderators in a way that would require action of me that goes against my conscience and, in my view, the best long term interests of this and other sites. I am requesting to resign as moderator because I cannot support the new company policies nor the way they treat their volunteers.
For the long version please see the somewhat wordier explanation I just posted on Christianity's meta site.
I'm sorry it has come to this, and it really has been a privilege to serve this site along with the entire crew of current and past moderators. I will sincerely miss that, and I wish the best for the site.
