Here’s a slice of red-toothed rabbinics from Matthew Wagner, writing in the Jerusalem Post. It begins:
“A Jew who sells land to an Arab in Israel should not be allowed to lead prayers in synagogue, should not be given the right to make a blessing during the Torah reading, should not be counted among the quorum needed for public prayers and is considered an abettor to the enemies of Israel, according to a halachic decision issued on Monday night by a group of rabbis calling themselves ‘The New Sanhedrin’.”
