A different response, which comes from a different angle to those pointing out that Marxism-Leninism is not fascist:
The word 'fascism' is used so fast and loosely outside of a technical context that I wouldn't say one interpretation is necessarily right or wrong. It depends on context. (Incidentally, same for 'socialism', even principled well-read communists can't agree on a definition.)
For example, if we're talking about the actual Fascist ideology (think of Mussolini and associates) then I would even hesitate to include Nazism due to the very different roots: they're both nationalist anti-liberal anti-democratic, anti-socialist 'third way' ideologies and they did ally in the war, sure, but to group them both as 'fascism' trivializes core differences in how they formed, why they successfully formed, how they appealed to their followers (fascism actually recruited many self-identifying socialists in Italy and its important to recognise why to prevent it), and why they were ultimately antisocial and unsuccessful in their goals.
This isn't just some academic masturbation nitpicking or anything: I believe that the ignorance of Classical Fascism by lumping it in with the far more obvious and baseless idiocy of Nazism makes it harder to recognize and counter, especially when neo-Nazis are such ridiculous cartoonish farces. Fascism stemmed from National Syndicalism and has core economic ideas like corporatism (from 'corpus') that could fool people, and sounds much less stupid that Hitler's bizzare esoteric fantasies about Aryan racial supremacy: even Mussolini considered Hitler crazy.
The point of me making this distinction is that the dictionary definition you gave isn't even wrong in describing fascist ideologies, but, I don't think that list of common traits should be mistaken for a definition. Those traits are the results, not the foundation of the ideology, and a neo-liberal state like the USA can easily match many of those traits despite being a very distinct ideology. Any you will absolutely see people saying 'USA is fascist' as a shorthand for nationalist, racist, imperialist, oppressive, blah blah blah, but it's definitely not post-National-Syndicalist faux-socialist corporatist collectivism. We should obviously fight both but they are not the same and manifest differently.
