Honestly, I would venture that we are way beyond the Holocaust in many ways already.
Given the NSF's role in all this, we are getting a massive discrediting of Communism, however, unlike e.g.
Twilight of the Red Tsar, this will be a boost for the center and not for the right. Mayhaps, China starts calling itself Maoist instead of Communist, Germany extends the ban on the Swastika to cover the Hammer & Sickle as well, Visegrad countries start banning "anti-democratic" parties etc.
Somebody like Bernie Sanders, who quipped “Let’s take the strengths of both systems. Let’s learn from each other” about the Soviet Union, Gregor Gysi in Germany etc will never achieve their OTL fame due to their "guilty by association" in the eyes of the public, while others like
Corbyn, Thorning, Cossutta may be much more moderate in their political personas.
