why do you find feet-washing indefensible? ddm's gaslighting aside, jesus washed the feet of his apostles in front of the rest of them as a demonstration of humility, encouraging them to continue the tradition (what you and ddm refer to as "virtue signaling"😉.
i'm aware you're an atheist, so if you just hate religious things, fine. but again: why do you find it indefensible?
