White supremacy builds upon Jew hatred and they are intimately connected. A Jewish person who literally willfully helped the Nazis was… a Nazi. A Black person who uses their platform and as a hobby goes out of their way to parrot the values of the KKK is… a white supremacist.
I think you’ve come down with a woeful case of “You’re saying mean stuff about my friend and since I like my friend you must be wrong!” Lil hint for you here bud, your friend is awful, and he is a hateful bigot. Alas, let us just hope for your sake that it’s not true that “you are the company you keep” 😉
Take care!
