Church ladies are like that. Their strange creatures. Their kind of swan-like. They look all prim and proper and everything an expected woman in society should be when
really their nasty towards others who are unlike themselves.
That's been my experience too, I've seen both sexes practice this though. Christianity is, more often than not, worn as a mask to hide the true persons faults.
The last shop I worked for, the boss and his wife were "devout christians". They were the cheapest, stingiest people I've ever seen. Most of their employees were either Mexican or Vietnamese, they complained about me being a white guy who was "used to getting paid Aerospace wages".
They showed up to work in matching Porsche Cayannes, The boss had about $500,000 of "toys" (race cars and dune buggies) in the shop, and his wife had a $6,000 boob job and a $20,000 diamond studded cross around her neck to show how much Jesus loved her.
Fucking hypocrites!
