Horseshoe theory isn't real, Hitler and his fascists had to actively pretend to be Socialists to get votes - that's not "horseshoe theory" it's fascists actively lying.
Fascism defends corporations, capitalism, and the wealthy. It's "Capitalism's immune system". Hence it requires deception.
Socialism defends the workers and community, It's the Poor's, working class, and underprivileged's immune system... Then only in later or it's own abusive, incomplete, or corrupted forms can it be weilded as the party/Authoritarian's immune system. Only when it becomes a state based fascism is horseshoe theory credible.
It's the lack of democracy that is the difference. Democratic systems favour the majority, only when they fail is fascism produced. Nothing to do with Socialism (which requires a form of democracy where the proletariat majority is supposed to dictate what is to be done).
"Elite Panic" is an example of this. The wealthy minority are the status quo, the community is the rest of is.
It's when that majority ceases to get a say that socialism is dissolved and a state authoritarianism can take over. But under honest analysis, that's a new elite having taken over, NOT Socialism. It's Socialism in name only, state fascism or authoritarianism in actuality.
"Elite panic"* is a term coined by Rutgers University researchers Caron Chess and Lee Clarke to describe the behavior of members of the elite during disaster events,[1] typically characterized by a fear of civil disorder and the shifting of focus away from disaster relief towards implementing measures of "command and control".[2]
Further research from Scott Bonn suggests that a cozy, mutually beneficial relationship between the news media and political elites plays a significant role in moral panic processes. He draws on prior studies to conclude that the news media and political elites ("especially presidents") work in tandem in the generation of moral panics and societal issues, thus constructing and crafting policy and public concern in relation to their own priorities.[3]
Wait, are you sarcastic or serious? Because to antifa it's well known from history that the liberal state is ineffectual in fighting fascism and doesn't mind flirting with fascists.
