Joe, Shapiro is also friends with Gilad Atzmon, who has proclaimed that he follows a strict diet – “I eat anything but kosher”. He is willing to deal with someone who hates everything Jewish in order to bash Israel.
Shapiro has never said anything against NK, and has publicly bashed Israel, in front of non-Jews. He is inciting non-Jews against Jews, and likely can be considered a rotzeach.
As for Feif Un, we aren’t neighbors. We are friends, and used to be co-workers. I met him in college. I also introduced him to Rabbi Bender, who he now admires very much.
