You guys's relationship appears too toxic to get a resolution here. Let me intervene. I don't think the first paragraph is really relevant to anything FD was saying. Many European right-wingers are considered left by American standards because there are inequality-reducing elements of their economic systems that are too popular for them to try to cut or they've genuinely accepted those elements as being good. Since the spectrum relates to one's position on inequality and hierarchy, those positions are left--in some cases, to the left of the more left-leaning party in America.
I haven't seen Trump criticized for not being a TRUE right-winger, though I have seen him criticized for not being a true conservative, which is different. Conservatives philosophically believe in the received, unstated wisdom of society and are thus cautious about making large or fast changes in society. That doesn't describe Trump. The movement has been moving toward favoring increasing American hegemony and has at least pretended to support balanced budgets, which also doesn't describe Trump. It's also favored stronger moral leadership, which also doesn't describe Trump.
Monarchy is the original right-wing cause, and Nazism is a kind of form of that. Obviously, the Nazis weren't big on the idea that we're all equal. American rightism is moving in that direction--before Trump but he does represent another step. There's a sense on the right that ethnic/racial demographic trends are dooming the GOP in fair democratic elections, and thus we need less democracy and we need to try to slow or ideally reverse some of those trends. These are obviously right-wing positions.
