Calling for the murder of Jews in America for what Israel may have done is not protected by the First Amendment.
Of course, imams and mullahs all over the world scream “death to the Jews!” every day, so Mossad would have their plate full trying to take them all out.
Making an example here & there probably works best. Get on Mossad’s radar & spend the rest of your life having someone else start your car.
