You think it’s half? Most of the conservatives I know are tangled up in peripheral issues. Liberty is a vague concept. It describes the absence of something. It’s hard for the literal-minded to envision—too abstract.
Unless it’s venerated from elementary school on up, it doesn’t have an emotional nerve cell to support it. And guess what? It isn’t anymore.
They do not know what Liberty even would mean.
Of course a vacuum won’t support Liberty. You need a positive ethic that people support for a whole different reason than because their government tells them to do it. Christianity alongside a smaller but still beneficial presence of its ancestral Judaism admirably served that purpose in America for centuries.
