If I remember correctly, fascism was a very disorganised "belief" (couldn't remember a more proper word) in the beginning, including people from all over the political spectrum, but it changed over time as more and more people found themselves exluded from what made a "true" fascist. I know that at lest the Fascist Manifesto contained rather many sociqlistic and progressive opinions to ponder to the still strong communist/socialist fascist wing (I believe it was written somewhere around the 1910s, don't want to check it now as I'm phone browsing, but my point is that it was quite long before Mussolini). I also believe Mussolini even made laws for gender-equalizing the country right after he took over to calm the strong women's right movement that supported him, but I might be remembering that wrong, or it might be a myth.
Anyway, to the point: "Mussolini's" movement needed to weed out opposition within the fascist movement, so they needed to both limit what a true fascist could be and create an enemy for the people to rally against - making the commies and socialists the diametrical opposite of fascism would not whip up hatred against one of the bigger ideological contenders for power in Italy, it also meant people within the movement had to take sides, and dealt with the factions within the movement that might not support it. So fascism, over time, was streamlined into a strictly nationalistic conservative ideology opposed to the progressivists and socialists.
ChairmanPoo: You've pretty much clarified what I already thought. Didn't the original fascists start out fairly left wing in their approach but showed their shift to the right in siding against the workers during strikes? Most fascists seem to at least garner appeal though appearing socialist. Even the British National Party are fairly left leaning (compared to the other parties) and pro community. This is part of the reason hard times gets them more votes.
It's more the blatant scapegoating of immigrants as the cause of all problems (which, sadly, seems to be creeping into mainstream politics here too) that wins them a few votes here and there (although it should be pointed out that their vote has completely collapsed recently, and that the Party is basically completely financially insolvent).
And, unfortunately, we're repeating exactly what happened in Europe during the decades before WW2. Europe is conservating itself again, only this time, instead of putting the hate on socialists/left-wingers, jews, and Romani, we're turning against Arabs/Africans/muslims and Romani instead (or again, or still, for the Romani). This is honestly some of what scares me the most when it comes to the future.
Hopefully, it's just my youthdomly inexperience blowing it out of proportion. But it still scares me a lot.
