Socialism and Fascism - what they are and are not

Hi everyone, I get trolled from time to time on Twitter by various far right types who object to a particular video I did years ago which states that Hitler was not, in fact, a socialist and did not , in fact, have socialist ideas. Here I revisit the argument, though I doubt it will do me much good.

Anyway, would love to hear your thoughts (unless you want to tell me he is a socialist, and whilst I'm all for free discourse, you should know that I've heard this one before, lots).
