A Karen of many titles? Pearl Clutcher. Morality Police. Busybody. White Feather. Bible Thumper. Baizuo. And the animal trifecta: Sow. Nag. Bitch. But they all mean different things. They're titles to be placed on the Karen. A bible thumper can easily be a Karen, VERY easily, if they're trying to press their views upon others in the public sphere. But if you use Bible Thumper on its own, it gives a different mental image. They're still using the tiny bit of power they have to give others a hard time, but it's not usually bound to a chain-of-command like a Karen is.
