Of course they should resist the use of violence by others.

I'm merely suggesting the French shouldn't violently resist people coming to France and peacefully selling weinershnitzel and saurkraut to people who enjoy these things.

I don't think you'll get any principle out of this beyond something like "my preferences are the best preferences."

[harryh → Natsu]

In general the right of people to do as they please as long as they aren't infringing on the rights of others isn't considered a mere "preference."

[Natsu → harryh]

That would work if deciding which things are and are not rights was not itself a preference. You can say that you have some axiom which informs your decisions, but you may have some difficulty proving that this axiom is superior to all others, or all others known (and in which logical framework?).

In practice, this usually ends up selecting for the preference to simply not care about any of the above.
