Also, among libertarians in general there is prevalent the peculiar notion that every political claim has to be justified on libertarian grounds or the person making the claim is excoriate. All must be within libertarianism, nothing outside libertarianism, and (especially) nothing against libertarianism. This keeps innovation to a minimum, since everything has to be justified on the same grounds, and handicaps attempts to actually accomplish anything concrete, since situations are rarely cut-and-dry by libertarian standards.
