Do you think fascism is something unique? Different from capitalism in some way?

Fascism is not unique or different from capitalism. It is capitalism converted into a format that allows the highest level of extreme violence to be carried out against its enemies. It occurs when capitalists feel threatened by socialists, gaining monetary support, media and backing from the bourgeoisie who recognise the need to use ultra-violence to exterminate the revolutionary threat to their existence. It is not a separate or unique thing to capitalism. It is still capitalism.

We only need to look at the places where fascism was not defeated to see proof of this. The fascists won in Spain and in Chile, they were not defeated like they were in Italy or Germany. What happened there? Did fascism ever become anything unique? No it did not. The fascists maintained and even increased capitalism, the term "privatisation" comes from Hitler himself. Over time in the countries where fascism won, once they defeated the left, exterminated them and their leadership, rendered them inert and no longer a threat to their bourgeoisie, these countries simply morphed back into liberalism which is a more efficient form of exploitation and extraction. Once the ultra violence was no longer required they morph back into "friendly" versions.

It is this that you are seeing when we discuss fascists and liberals in the same breath. They are allies in their support for capitalism and opposition to socialism.

And who exactly becomes the fascists? They don't simply spawn out of a spawning pool. They were liberals until the media, money and influence of the bourgeoisie backing the conversion of society to fascism successfully radicalises them to the cause.
