So basically, any form of totalitarianism is left wing, and communism is fascism? Even though a good part of both German and Italian fascism, both right-wing, was premised on virulent anti-Communism? You’re tying yourself in knots to make things comport to a definition only you use.
At the level of the nation-state, pretty much all forms of totalitarianism will be a form of left-wing (by the economic definition). That was one of the great realizations by the late, great free market economist Milton Friedman, that political freedom and economic freedom are inextricably interlinked. It is pretty hard to maintain a dictatorship if the private-sector can tell you to take a hike. At the non-nation state level, oppression can be right or left-wing, for example you can have very economically right-wing racists who hold the conspiratorial belief that the Jews secretly run the world and cause all the wars and the Federal Reserve is a primary instrument of such and have no problem oppressing the rights of non-whites, gays, etc...but in order to establish an actual authoritarian government, they will have to reverse on that whole free market absolutism thing.
There are some exceptions, but they are rare: Singapore, which is an authoritarian government but a free-enterprise economy, but Singapore is a city-state. Pinochet's Chile is another one, but going free-market under him it could be argued eventually led to his being removed from power after sixteen years. Modern China is another, a mixture of socialism that has gradually adopted free-enterprise, but since Xi made himself dictator, the CCP has since cracked down on much of the freedom of Chinese companies as it was viewed they were acting too independently. But otherwise, almost all authoritarian systems are socialist or involve a heavy-handed form of government intervention in the economy. This, BTW, is part of the reason why the West was so pro-help China, because of the belief that by growing the Chinese free enterprise economy, it would eventually lead to the transition to democracy. The CCP is well aware of this and has acted as needed to maintain its power.
And yes, communist systems it could be argued are generally a form of fascism. Communism the fantasy ideology is not, as in communism there is no state or business owners, everything belongs to everyone and it's all one big happy communist family, but to try and create it, you have to implement what basically amounts to a form of fascism.
That’s some twisted logic. Trump is a fascist. Fascism is premised on right-wing nationalism, often tied to an idealized past. That’s why the Nazis got so into an idealized mythology of racial purity and Paganism mixed with Christianity. Make America Great Again is practically a carbon copy.
If Trump (and MAGA) is a fascist, why do his positions so undermine such a system? (free-markets, reduce regulation, adhere to Constitution, gun rights, keep America out of wars, etc...?). And again, you can't just throw out "right-wing" without a definition. The Nazis for example were most definitely not strict believers in the rights of the individual and limiting the powers of the State. Their belief in racial purity was also scientific in nature (well pseudoscientific but no one thought it that at the time), via the (pseudo)science of eugenics. In the U.S., much of the early 20th century American Progressives were it could be argued a form of light-hearted fascist, and they leaned (economically) left. They disdained the limits of the Constitution, favored state control and top-down rule by the elites, seeking to remake America into an administrative state. They also were strict eugenicists. Planned Parenthood, for example, was founded by a eugenicist and run by a eugenicist for many years. In Buck v Bell, when the SCOTUS ruled that the State could forcibly sterilize people, numerous states then enacted such laws. California, being the most progressive state, performed more forced sterilizations than any state in the union. The Nazis took all this to a super-duper extreme, actively conquering other countries, trying to conquer others, and rounding up and executing all the "subhumans."
All of that heavily deviates from the right, which favored individual rights and limiting the powers of the State and rule by the people as opposed to experts. Also the right traditionally was very suspicious of militarism. This goes back to the Founding Fathers who were suspicious of standing armies and because the right correctly saw that militarism requires heavy state involvement and/or control in the economy. After WWII, we saw a new form of right emerge in the form of the neoconservatives, who generally were for individual rights, limited state power, free enterprise, but also for a very powerful standing military and okay with whatever state intervention was required to maintain it. This was in response to the experience of WWII and the onset of the Cold War and the recognition that the old way of having a tiny standing military wasn't realistic.
And before anyone starts dusting off the artillery, no I am not saying if you are a left-leaning Democrat or believe in abortion or give money to Planned Parenthood, you're the equivalent of a Nazi, I'm just pointing out how tossing out the "fascism=right-wing" claim is way overly simplistic.
