It's because they're joined by us anti-crime people against the Islamic fascism that's increasingly taking over parts of western towns and countries, and that cause is historically unbiased politically, as no one has ever benefitted from an Islamic influx.
When demonstrations against unprecedented mass immigration, and for National secular sovereignty appear, they get the "far right" headline. According to that, half of Germany is far right.
The Jew-hating thing that the far-right has always been known for, just like the left is now, seems to be in the background. No Synagogue or Jewish gathering in sports, funerals or commemoration of WW2 victims are in danger and guarded by police or military bc of Nazis.
Atm the entire right is preoccupied with the most immediate threat - those who are still actively hunting Jews in the west as well - Islamists.
