Yup. Camel's noses should always be shot. Otherwise they creep in more and more.

Some examples that come to mind:

Look how the exception for searches at border crossings has expanded.

The use of actions against licenses for behavior that has nothing to do with the license.

The use of permits to get companies to do things only marginally related to the purpose of the permit.

The encouragement of universities to expel those accused of criminal acts--just because the punishment isn't jail should not mean the state can hand it off to a kangaroo court.

Pressuring financial companies to cut ties with disliked things. (For example, getting Steam to remove games with any whiff of incest. Either declare them illegal or don't take action against them!)
