I caught a few “errors of enthusiasm” too and had also first heard of the prophesy at Aish Discovery... a few years after you my G-dly brother. The thrust of the class is spot on.
I haven’t heard of similar phenomena for Communism, though you can probably find some (kosher) Bible Code site that has “Stalin” or “Lenin” “Marx” “Democrats” etc with a correlation.
There is a well known story (in Lubavitch circles) that at the time of Stalin’s death, the chassidm were at a gathering with the Rebbe where he incited them to stand up and shout Hurrah! (double meaning-— “Hurrah!” as we understand it...a cheer, and hu-rah (He is wicked). The rest is untold history. See here:
And I just looked it up and it happened at a Purim gathering ;)
Lastly, remember that the gematria of Amalek is “safek” Doubt. Amalek always comes along and tries to cool the inspiration of a Torah believer. “Oh, you just came through the split sea and are on your way to hear G-d’s voice ey?” “You are the same guys who were idol-worshiping slaves in Egypt weren’t you now?” [then came Amalek and attacked the Jews in the desert...] Amalek, spiritually, is coldness. They come to dull the enthusiasm and passion for G-d. So in a funny way, Mr. Watchman is right about Amalekites on FR! Ha ha!
