Resurgence of nationalism in Europe is a blessing in disguise. Truly they will want to distance themselves from the Holocaust, and I think most peoples can do that safely.
Will they now:

They disown the Holocaust, because it's electorally convenient (like they support free speech only when it's convenient for them). As they faciliate anti-semitism, so it is particularly important to put up a veneer suggesting otherwise. But anti-semitism is rife in European nationalism: they're about white skin and Christian culture and Jews will always be outsiders to them. The other thing is that I also care about the rights of a lot of groups other than Jews that European nationalists consider outsiders to be suppressed (homosexuals being an obvious example). If you don't consider the growing threat to them a problem for your "blessing in disguise", that's your prerogative.
Communism is ever-present in modern Marxist thought, which has overtaken western universities and governments. Critical theory lead by the Frankfurt school for example can be read as Marxists disguising themselves after the utter moral and actual failure of their ideals and policies... You can shroud your shit in post-modernism, but people will still smell shit whenever they view it, unaware of its influences and past.
I think people who don't have any noticable experience of Western universities have a very strange idea of what goes in Western universities. I work in a Western university, and I don't know a single Marxist in it. Going back through my full ~20 years working in Western universities, I have known precisely one Marxist colleague.
It's fascinating to read an Israeli Jew propounding an anti-Semitic conspiracy theory. The Frankfurt School were Jews, and they were openly Marxist - they didn't disguise themselves. And they certainly didn't try to create a secret plan to wreck Western society.
Although the key thing is to consider what Marxism is. Firstly, it's sure as shit not postmodernism, because Marx was as modernist as they come and postmodernism was explicitly a reaction to the failures of modernism in the early 20th century. Marxism is not communism, either: Marx didn't even describe communism, except in very vague terms. Much as Marxism has an associated idealised notion of how society (should) end up, ultimately it's a small part of the whole.
Marxism is a very broad collection of theory about stuff like working class empowerment, criticism of late 19th century Western society and capitalism, and ideas about how societies develop. It is perhaps inevitable that at least of some that material turned out to be useful or accurate. Obviously, some of that was therefore incorporated into wider knowledge and understanding, built upon and developed, just like happens with all such thought. Most of it was social so ended up in sociology, but there are bits in economics and elsewhere too. But this isn't full on Marxism. Some of it is new intellectual movements with some element of Marxism. Or you can have "Marxist economists", for instance, but you'll find a lot of them don't support political Marxism at all: they just believe various Marxist principles about the relationship of labour, wages, capital, etc.
What the current "red scare" is really about is a lot of poorly developed attempts to associate leftish wing ideologies with Marx (like "cultural Marxism": dog whistle and antisemitic conspiracy theory which collapses into gibberish when tested) and then say the Commies are trying to take over. And hey, just like in the 1930s, here come the nationalists to save us from the red peril, preaching to save society by excluding and repressing anyone they don't like the look of.
