We're back to "language games," it looks like. You're using "Nazis" and "fascists" to mean what YOU want these words to mean, and this makes it impossible for people who define these words differently to have an meaningful debate with you.
For example, you clearly choose to define "fascist" and "Nazi" as meaning leftwing, whereas most sober historians would call them "rightwing."
You're also choosing to define "fascism" by referring first & foremost to fascist economic policies, which in some ways actually were similar to the mix-economy, basically capitalist policies that many modern progressives favor.
But fascism and Naziism as defined by Mussolini and Hitler were not simply ECONOMIC philosophies or economic movements. Both of the great fascist leaders of the 1930s championed beliefs that most modern progressives consider immoral & disgusting:
-- a belief in war as the "highest form of human endeavor"
-- a belief in racism and racial supremacy --- to a limited degree in Mussolini's case, to a really fanatical degree in Hitler's case
-- a virulent anti-Communism and anti-socialism, with Mussolini's Black Shirts first gaining power through violent & illegal attacks on leftwing labor activists in Italy in the 1920s, and with Hitler proclaiming in "Mein Kampf" his ferocious hatred for Russian Bolshevism.
Not to mention Hitler's long-term plan to win "lebensraum" for Germany through a basically genocidal invasion & colonization of Slavic nations to the East.
-- a contempt for political democracy and a near-worship of governance by an all-powerful Ruler -- e.g., Mussolini as "Duce," Hitler as "Der Fuerher"
-- a political base that in Hitler's case, anyway, was partly centered in an economically insecure lower middle class, and that focused its "socialist" hatred on wealthy Jewish capitalists, even as Hitler was reaching out to ultra-conservative German businessmen like the Krupps and the Thyssens for support.
-- an explicitly anti-gay and anti-feminist politics, even though the Nazi street-fighting group the SA was initially led by a gay man, Eric Roehm, and originally included many homosexuals.
In contrast to Hitler & Mussolini and their followers, however, modern American progressives are generally
(a) antiwar, or at least suspicious of excessive militarism
(b) anti-racist and egalitarian in their politics
(c) pro-feminist and pro-gay
(d) in favor of "one-man, one vote" democracy and against the cult of the Supreme Leader [although admittedly, some progressives do sometimes engage in hero worship regarding political figures like John F. Kennedy & Obama.]
(e) not obsessively anti-Communist, as Hitler and Mussolini both were, but more inclined to seek diplomatic compromise with the USA's political adversaries
(f) not especially rooted in the more insecure parts of the American lower middle class, and not inclined to demonize unpopular minorities in order to satisfy lower-middle-class fears & hatreds.
To summarize, modern US progressives have almost NOTHING in common with European fascists and Nazis of the 1930s except for their common recognition that "free market" capitalism, left completely to its own devices, doesn't work automoatically & often leads to economic crisis.
Like Hitler & Mussolini, "progressives" today are in fact smart enough to recognize that a pure "free market" capitalism will often bring disaster to society. Just as global capitalism did during the 1930s, obviously.
But aside from that, US progressives today are almost totally opposed to fascism as a political movement dedicated to war, racism, sexism, imperialism, and the replacement of democracy with the cult of a Supreme Leader.
I'm biased, but I sincerely think that for those "fascist" and "Nazi" characteristics, you'll find much more support among modern US conservatives.
