I won't comment on the Alzheimer's or Dementia........ I will say it's possible that Mr. Stahl's letter misrepresented his feelings by linking Judaism and Zionism as perpetrators of a "false flag" plan to utilize anti-Semitic actions to garner support for Zionism.  IMO, there's a real difference between Judaism and "hardcore" right-wing Zionism.  I, as I note in another post, have concerns with the treatment of non-Israelis by the Zionists, but separate that from my feelings about Judaism.  IMO, the anti-Semitic actions we've seen increase since Trump's election are, in fact, the actions of, guess who....................anti-Semitic Americans.  Occam's Razor strikes again.   Gary Crum
