the problem doesn't reside in the "rightwing brain" in terms of structure, but rather the flawed and inconsistent structure/construct of their immorality/amorality that results in such high levels of disgust for their ideological opposition. They live in denial of all the facts that undermine their povs on those matters and more, but most importantly, in denial of who and what they are all that defines them to be.
Deflections, projections, scapegoating, etc, are all denial tools that alleviate their burdens of conscience, and keeps their disgust flowing outward as opposed to inward where it belongs. Lying to themselves is necessary, and the mortar that keeps the wall of denial standing.
The dynamics of it all isn't that much different if at all, from what the German people collectively underwent decades ago.
One can only wonder for example, had it been some politically neutral figure rather than the despised Al Gore, that took the helm of the global warming awareness movement, what that debate would look like now, or the public opinion polls would show on the matter. Similarly, one could wonder what the modern "con" mind would look like, if they weren't on the wrong side of almost every political issue of significance past and present that has led to forward progress and less human misery. Much like the greatest lie the devil is said to have successfully propagated -- that he doesn't exist -- the modern con has to lie to the public and to themselves, to pretend that their sad and sordid record doesn't exist. Their record of failures and the immorality component of much of it, is transmuted by their mental alchemy into successes. This is why despite all the evidence that record represents, they still lay claim to the moral high ground and a monopoly on mensa membership. It's also why they have tolerance for chick-fil-a and muslim-bashing video makers, but no tolerance for those who object to them.
All of which is why I've long been disgusted with, and loathe and despise them. The difference is of course, mine can be justified because it doesn't have bigotry as the proximate cause -- unless intolerance for that kinda intolerance, or hating haters is "identical to on a moral scale, the kinda bigotry they embrace and gladly live with.
