[These guys?]
If so, kudos to them. Heck - we supported the Russians even though they got WWII going by allying with Hitler in the first place. Compared to the way the Russians gave the Nazis their head start, I think these Ukrainian LARP’ers, who haven’t actually killed 6m Jews, are amusing but fairly harmless. The fact that they are risking their lives to defend a Jewish president who presides over a capital city run by a halachically Jewish mayor, is evidence enough that they are using these symbols mainly to annoy the Russians.
