"Improving/preserving wealthy elites will naturally benefit fewer people.
These are facts, with evidence"
You are implying, that it is a fact that right leaning people want to preserve wealthy elites.
But this is not, what I heard from right leaning people as their goals.
"Capitalism, or more specifically inequality created the tribes."
And I believe, tribes existed way before capitalism.
So I believe, that you are indeed quite extremist in your ideology, if you know as a fact, that left is good and right is bad.
There are many, many different contradicting views and concepts on the right as well on the left. To some I agree, to many I do not.
But as an example, the nazis are considered quite right usually. But it is nationalsocialism. The concept of the greater good for the people (of one race). So they are left then?
I rather think the whole left right concept is flawed and not helpful.
