GEN1380 If a reasonable fear exists that wicked person who cannot be deterred will actually cause harm if not treated properly, then it is permitted to extend [] honor, i.e. standing in his presence and acting with feigned trepidation. However, treating such an individual with genuine respect, such as by speaking favorably of him out of his presence, is forbidden under any circumstances.  A rabid anti-Semite has become very powerful. The Jewish community may attempt to temper his hatred by means of gifts, etc. [this verse].   EHRMAN 104
