I know David Irving isn't the best name to bring up... Practically the worst, however while I haven't read it he did write a book on the Hungarian revolution, one that my grandfather fought in.
Now, my grandfather never really liked to talk about life under occupation, much less the revolution... But he did talk at length about politics.
My grandfather was, as some might call, a patriot. He wasn't a 64 Counties type person who wanted to see the Kingdom of Hungary rebuilt... But he wasn't a liberal. He hated the Communists with a passion, claiming that 80% of the members were Jewish and that they were the ones who sent the innocent to die in Siberia.
So... Here's where things get muddy. I'd like to preface by saying in no way am I a historian with extensive knowledge, merely providing my hypothesis based on second hand sources.
My grandfather wasn't wrong, from what I've gathered. Hungarian Jews fled to the Soviet Union as soon as labor battalions started getting formed early on in the war. They rode out the war as best they could in Russia. Upon returning, some may have led the advance back into Budapest in 1945.
Now, if you're a returning Communist Jewish or otherwise... Who do you trust in this new Hungary? You're living in a land which was once heavily fascist. Why not trust the people who came back from Soviet Union?
These people get jobs in government as everything from secretaries to mailmen to criminal case managers... To people sending Hungarians away to Siberia for former ties to the fascist regime. My great grandfather was a mailman and got 6 years.
Propaganda also plays a part in this, as after the revolution that is what people were told; that it was of a fascistic, anti-Semitic nature. The lynching of AVH members, the Dudas militia... It's a very strange thing to ponder.
My personal opinion is that no, by no means was it anti-semetic. It was not intended to be, all that was intended was to break the chains of a regime that did nothing but rob and steal, broke up families and spread ideology through intimidation not unlike those they rallied against.
Sorry if this is too controversial :/
This is not a proper answer but since no one else answered, fuck it. Note that many Hungarians are anti-semetic, and have been since before the communist era. To varying degrees, but I'd say the vast majority hold a negative opinion of Jews, so the revolution would've been in a way Anti-Semetic, but only because many of the people taking part in it were Anti-Semetic. It's purpose and goals weren't anti-semetic though. Also, can I ask whether your grandfather hated the communist regime the entire time it lasted, because from what I've seen it's been the liberals hating on the Communist era and the Nationalists saying how it was so much better compared to now.
