Yes, there exists anti Semitic Jews such as Marx, Sanders and Soros. The Jewish apparatchiks sitting around Lenin (6 out of his 13 sorts of czars) were also anti Semitic leftist Jews.
However Salazar is a peculiar kind of antisemites, the kind that organizes the Mexican illegals who are extremely racist and are currently reviving the KKK in America that was dying,
Let us not forget that German Ace Hartmann who spent time in Soviet camps and never apologized for his aerial victories to the Soviets spoke about those vicious Nazi aparatchik of Hitler who no sooner entered the camps started praising the genocide of Stalin and snitching on Germans not repenting and attempting to escape the camps.
These Nazis who faked repented into the next genocidal methods of Stalin were called ANTIFAs. The same Soviet program of converting quickly the worst of Nazi thugs as best friends of Stalin is exactly how Alinsky converted the KKK democrat to Stalinist thugs in fake Clinton like repent.
There was never a switch of the KKK Democrats to Republican, the switch was to stalinist antisemitism
You have it backwards. Antifa ( Antifaschistische Aktion) was the paramilitary arm of the German Communist Party in the early 1930's. They pre-date the Nazis coming to power.
