They're an excellent crystallization of why most aspects of right wing reactionary movements run anywhere from completely retarded to dangerous, and more often both. The only people capable of matching their level of stupidity or just flat out mental illness and self absorbed denial of reality are trannies.
>does it discredit it
Well to answer the question that OP posited I would say that yes, it certainly does. Moreover it shows the futility in it because virtually all the last batch of right wing leaders from Bolsonaro to Boris Johnson to Trump are themselves neoliberals anyway, and all their economic plans ultimately rely entirely upon globalism with the only difference being their appeals to populism and half baked notions of increasing local industry because of sheer greed. Like what do you think is going to happen to all that Brazilian timber? Or Made in USA industrial goods? None of those things are explicitly for internal markets but rather finding ways of dealing with foreign trade imbalances.
Moreover it has also explicitly revealed how dangerously retarded they all are for us to now be in the middle of a global pandemic, with them wishing to reap the fruits of globalism while doing fucking nothing to shield us from the fallout. Trump actively fucking us with his minor spending cuts to literally the only nice things we have like the CDC, NASA, scientific particularly global warming related budgets such as his moronic dick waving with the weather service all of all things, while giving tax cuts to the exact same globalist billionaires such as himself and ballooning our entirely globalist oriented military, is as very nice shining example of that. It should be noted that Trump in particular is a globalist who has properties all of the world and has been counting on the sheer ignorance of rubes with his lies and emotional appeals while enriching himself and his family with globalist deals all of the world from China to Saudi Arabia to Scotland.
So do these things utterly discredit reactionary movements? Of course they do. Because these are the movements reactionaries tend to give us and I find it no smaller irony that the very people putting these neoliberals into power literally don't even realize that "neoliberal" is literally another word for a brand of Capitalism and that they're doing all this while shitposting on an international imageboard. What it ultimately is saying is that globalism of sort or another is completely inevitable and the only differential is in which ways you've chosen to interface with it, which in their case is being as pigshit ignorant bydlo as possible and massive hypocrites to boot.
So like I said, yes it is inevitable and the only real reactionary alternative left is becoming a primitivist of one sort or another. In a similar vein, I would say that "degeneracy" is not
inevitable however that is likewise no small irony that people on f'ing 4chan of all places should actually sit there to bitch about degeneracy while themselves being active participants in it, wherein the only real alternative to being a degenerate would clearly not to be to frequent an utterly morally debased community that was practically founded for jerking off to Japanese cartoons and that has been one of the sole lines of continuity of 4krebs to this very day. So I would likewise posit that in order to actively reject
such degenerate behavior and thinking necessitates you actively disengaging yourself from it, in like manner as to take a truly reactionary and anti-globalist position requires you to not be a participant in it. As such, the entirety of /pol/ exists as essentially an amoral morass of largely self absorbed and psychopathic individuals that has come to represent a form of radical establishmentarianism for stupid people. Those that are in power know this and know that said stupid people are always going to be vanguard for their establishment and a wellspring of easy exploitation and diversion from the actual problems inherent in the structures of the system itself.
I would lastly like to point out that quite possibly the funniest thing to me in all this is that a large degree of their sentiments and points of view could generally be considered leftist, except through a wildly self absorbed and racist lens and that has been successfully diverted into the aforementioned radical establishmentarianism rather than them ever becoming an actual legitimate threat to the current global order which would require their correct identification of the problem as being a Capitalist one, or of actually organizing themselves into a genuinely threatening force of organized subclasses who have totally rejected the establishment elites altogether, of which Johnson, Trump, Soros, Bolsonaro, Gates, Bezos, Adelson, Blair, King Abdullah, Putin etc are all members. As such it has fractured and demoralized them enough for it to never have occurred to them that a religiously based reactionary movement would be the far more threatening and dangerous one, although clearly it is not uncommon for them to have had the cognition that basically the only problem they even have with Islam and Shariah law is because they hate brown people and associate it with them, alongside the other frequent sentiment which is their utter hatred and disdain for Christianity that was likewise shared by the Gitler and lamentation that it is both intrinsically Jewish as well as being "soft" and of a more compassionate bent than a conquering ideology like Islam that theyve wanted, although either of them taken to its logical pure form is likewise a total rejection of this system and much of the things they hate, with the sole issue besides Judaic origin being that it literally requires them to not be a bunch of self absorbed sociopathic fucking assholes.
