Christianity is not the only belief system that divides itself up according to fine nuances of theology. Virtually all religions do that. And so do secular ideologies. For example, the Wikipedia article on “Libertarianism” cites six varieties. So if you are a libertarian, are you a libertarian conservative, a left-libertarian, a minarchist, an anarcho-capitalist, a geolibertarian, or (my favorite) a libertarian transhumanist?
Go here to see what each of those means: Libertarianism – Wikipedia, the free encyclopedia.
