It shouldn't be acceptable to glorify neither of: Hitler, Franco, Mussolini, Mao, Stalin, Fidel, Guevara, Hussein, Pinochet, Ceaucescu, Gaddafi, etc.
My point is that authoritarian murderers are authoritarian murderers no matter their political affiliation and should not be glorified. You can be against one extreme without supporting the other.
Although I'd say the tag kind of fits, but Bush is in another category. All the people I mentioned had in common the persecution, imprisonment and execution of their own people at a massive level and maintained power by force. Bush went after other countries and was voted out in the end.
