Here what you said:
“Lenin, Trotsky, Kaganovich and Yagoda killed 25 million - mostly Christians.
Does being critical of that make one antisemetic?”
I never said that being critical of Lenin, Trotsky, Kaganovich and Yagoda made someone an anti-Semite.
This article says that the Birchers got lots of criticism for accepting Jews into its ranks.
I am not sure it is fair to call them antisemites.
