>What's going on here. Seems to me this boils down to some people *liking* the idea of forcing religious people to do things they'd rather not, which is a story of petty bias.

Petty is the idea that the religious officials should take some of their own traditional medicine, forcing others to do what they'd rather not. Last such bit is that hunting is still illegal on sundays in some states - for religious reasons.

Revenge is just a reiteration of the deed which caused it, and is often indeed petty.
