and then there's the definition from countries too close to nazi germany and/or the ussr at some point in its history: a term they will politely but enfaticaly deny, always.
facism has aspects based on syndicalism, a subset of the socialism true, but its far from the defining characteristics of a true social equalization. syndicalism (and then facism) is based on categories within a society.
the best definition, used in a trotsky speach, is that facism is "socialism for the upper and middle classes". if you apreaciate the sweet irony you can clearly see why facism can never truly be seen as socialism. if you miss the irony, you should just call yourself alt-rigth.
Actual socialism has never, and will never, be implemented. People are not idealistic enough (most people just want to avoid work) and it is always the wrong people who grab power.
The creator of Fascism was Mr Mussolini, himself a member of the communist party in Italy.
It was only that Mussolini wanted to create a socialist movement independent of the International Socialist , the Komintern, which was controlled(and financed) by Soviet Russia, following the interests of that country.
So he created a socialist movement with the interest of Italians first, nationalistic. Hitler then copied the movement in Germany.
To say that nazis were not socialistic(and socialized the means of production) is like saying that Trosky was not communist because he was assassinated by Stalin.
Of course they were the worst enemies between each other, but there were not big differences in the way they planned the economy.
In the civil war in Spain, in the left side there were independent anarchist and socialistic leaders and they were killed by Stalin, not Franco.
Far too much effort is wasted arguing along the way.
- Individualism is squashed in both systems. The citizen solely exists for the state and is to be exploited as a worker or cannon fodder.
- Both systems had worker holiday cities for propaganda and constant reeducation.
- Both systems had many youth organizations for indoctrination.
- Both systems had nationalized radio.
- Both systems sent their opponents into Gulags/camps.
- In both systems, if you pretended to be a follower, you'd be taken care of (that arguably is the socialist aspect of national socialism).
National socialism did not actually nationalize companies, but they were certainly under control of the state.
The point is that while the ideologies were different, the outcome was not completely dissimilar (even antisemitism with purges was there under Stalin). National socialism had an overtly murderous ideology, while the marxist one pretended to do one thing and did quite another.
At most you can look at efficient surface similarities and say this ideology does not prohibit these actions.

Obviously NS is not 100% equal to abstract pure socialism, I think we can assume that everyone here knows that.
