Fascism is first and foremost genocidal Judeophobia. Anything else is secondary. Claiming that Fascist MUST be a white ring-winger advocating a strong State (I don't specifically refer to Trump) is exactly like claiming that a Fascist MUST be a vegetarian (like Hitler AND Albert Einstein) or that a Fascist MUST love Dostoyevsky (like Goebbels AND Franz Kafka). It is true now (take a look at Farrakhan and the "Squad") and it was true during the Holocaust either! Grand Mufti Amin al-Husayni was no white! Ernst Roehm was no right-winger! Flemish and Valonian Nazi collaborators did not want a strong, stable, unified, independent State of Belgium!
No it isn't. What reputable source says otherwise? The Italians were fascist before the Germans and had no great obsession with Jews. And, of course, many people have been anti-Semitic without being fascists.
Ask death camp survivors! The Italian Fascism turned genocidally Judeophobic at the very latest in 1943 More than a few "simple" AntiSemites later turned into genocidal Judeophobes. Mussolini did publicly make AntiSemitic remarks already at 1920.
What death camp survivors have made the claim? Can you cite any? Can you cite any source that backs up your claim because every definition you will read says different to you? And are you just going to ignore Italy, which was fascist before Germany?
In which you seem to acknowledge that there was fascism before it was heavily anti-Semitic. Did you read what you wrote? Which does nothing to remove the point that plenty of anti-semites haven't been fascists. I really urge you to read what is written by survivors and their organizations. They might give you a much needed history lesson about the right. There is a hell of a lot that has been written by them about fascism. I don't think they would appreciate you giving the word a private definition in an attempt to rewrite history. Seriously, try going to a holocaust forum and telling them that fascism isn't a right-wing philosophy!
I don't think anyone is saying that fascism requires you be white. In a western context, they are pretty much all white. I think most people are worried about fascists because they're not just fascists. They're other things as well like white supremacists, or advocate for some sort of ethnic supremacy.
Fascism has nothing to do with hating Jews. That's antisemitism. They're mutually exclusive although you can be both.
