I believe, that, in some cases, it isn't really "fascism", nor "oppression" which those on the left fear, so much as the reality of their immoral behaviors, views, lifestyles, and so forth.
And that's it's not really a case of fascism, so much as just a wake-up call from reality, it itself having a "fascist bias" to those on the left.
A left-wing degenerate, for example, may simply not like the idea of being told that pedophilia is wrong or evil, not merely just "socially unaccepted", that elements of society are naturally hierarchical, and that much of their misery Is self-created, as a result of their own immoral worldviews, miseducation, misinformation, and lifestyles, rather than a conspiracy theory invented by "rich cis white heterosexual male Christian capitalist NWO elites" designed to oppress them, publicly and privately, merely a case of society naturally rewarding moral, thinking men and women at the rightful expense of less moral and competent ones.
In the same vein, one of a degenerate, 6th grade education, to whom their favorite progressive blog or media network, marketed to those who's intelligence and education stunted at those levels, designed to exploit them by preying on their immorality, vices, and sociopathic lust for a since of victimhood.
They may be adverse, for example, to being taught that not being a fatuous consumer of degenerate mass media isn't an equal or better "lifestyle choice", than being a man or woman of some morality, character, and merit, such as one who is entrepreneurially minded, and more concerned with helping others is some mature, adult and sincere way (whether based on our Common Law's notion and concept of intentions, or so forth), requiring much in the way of personal development and sacrifice, as is the case of mature men and women, presently and historically who have stood the test of time, and manifested themselves as inspiring role models in whatever their endeavor of choice, from sports, to sciences, to arts, to business.
They might also simply be adverse to having to be told that indoctrinating their children into a worthless worldview, such as nihilistic atheism, progressivism, or materialism isn't just an "alternative lifestyle choice", but is morally and ethically wrong, immature, and ultimately worthless, easily debunkable, and deconstruct able, along with the false faiths, lies, misinformation, conflations, or other silly axioms upon which it is founded on or predicated on to begin with.
Instead having an aversion to society and its institutions, such as the Common Law system, founded on principles, including "religious" ones, such as respect for other people, their families, their property rights, their personal autonomy, and so forth - objecting instead to the notion of this religious morality, and the thinking men and women behind it, such as Supreme Court Justice Oliver Wendall Holmes, who helped to founded it and ensure it's perpetuation.
The very notion of law or morality of any sort being imposed upon them, when in reality that is the function of the law and those who make it, to impose it on those who have none, and refuse to do it themselves, living only for the satiation of primitive impulses, self-invented myths and fabrications to justify their immoral sentiments and worthless life pursuits, and drives, such as revenge - which the very law itself was intended to subordinate and take precedence over - much as the very notion of other institutions which they attribute to their sociopathic victimhood and persecutory conspiracies, whether families, traditions, healthy marriages, culture and civilization itself, even maybe the very English language.
Ultimately, what I believe they fear are just well-adjusted normal people, or any civilization of any lasting merit, and those of whom have been any lasting merit to them, from Mill to Kirk, would thankfully have no use for them, given that objections, say to the notion that pedophilia is morally reprehensible, not merely "socially unaccepted", or that genetics, psychology such as the evolutionary psychology of Steven Pinker and others, medicine, and biology indicate that sex and gender have innate origins, with most growing out of various "confusions" upon social maturation past adolescence, not requiring genital removal, nor being part of a "religious" conspiracy theory, just something universally observable enough that all sources, whether erroneously described as "religious" or "secular" have been able to make some measure of observations upon it, nor any childish myths of "trans people" having existed, or held any "sacred status" in ancient cultures only to be "repressed" as part of the conspiracy. or whatever silly little myths the cult members in question might like to content themselves with.
Ultimately, it isn't "fascism" that they fear; sure, fascists would object to this, but so would most well-adjusted normal people of some character, merit or decency - much as how a Communist might insincerely decry "greed" in a general sense (except for his own private property, in the case of the typical "bourgeoise" communist), but Jesus doing so does not make him a communist, nor does it mean he wants to "abolish private property".
So no, ultimately many or most of the conspiracists in question do not really fear "fascism", they simply don't like being told what they do, believe, feel and so forth, are morally wrong, by society and its institutions as a whole. If they want to believe, that pedophilia or pedastry is simply a "lifestyle choice", or that their inability to succeed in society isn't based on a "racist, white" conspiracy theory, but simply on the basis of better men and women who make up society wanting nothing to do with them, and for good reason.
MLK would want no more to do with these ilk than any white person of some reknown, such as a scientist like Marie Curie or Issac Newton would want to do with the KKK merely by the misfortune of having shared genetic ancestry with them.
Perhaps changing your behaviors, beliefs, lifestyles, and so forth is the better option, then you won't rightfully have to fear "fascism", "the law", or "society", in the sense of the meritocratic, thinking men and women who comprise most of it that has any lasting value or merit having to object to you, tell you "what to do" when you should be doing it own your own, and so forth. Nor will you have to appeal to your naïve faith in "the Constitution", not even knowing what your own "rights", "freeze peach", and so forth are to begin with, as per thinkers on the subject such as Supreme Court Justice Scalia, per Originalism who argues that it doesn't technically give you a right to utter "fighting words", including on the internet.
You fear that reality and the whole world is against you, because you are against reality and the whole world, it merely having a "conservative, Christian, or white" bias, depending on your flavor of conspiracy theory, or other archaic notions, ideas, dishonesties, or sentiments, from which you derive said silly things to begin with.
