Those who are opposed to the President lowering the U.S. Flag at half mast in memory of Nelson Mandela's death are bitter because:
1) they judge him based on his past and not his accomplishment as the former President of South Africa; and,
2) they view this presidential decree as a slight to Margaret Thatcher, former Prime Minister of England and a Conservative Leader, who recently passed away and clearly did not receive such presidential honors.
Judge him based on his past if you wish, but the way I see it if the world is in mourning over Mandela's death, how could the President of the United States not pay this foreign dignitary and icon of peace due respect? And since there clearly seems to be comparisons between paying tribute to Mandela and Thatcher, I'd like to know if folks who oppose this posthumous honor would be willing to produce comparative lists of what Mandela did not just for his people but for world peace compared to what Thatcher did. The only caveat: Leave Mandela's past out of it. Why? Because we already know of his actions as revolutionary. As far as I'm concerned, he paid for his crimes by spending 27 years in prison.
Let's see if folks are willing to be honest and then we can truthfully determine if Mandela deserves such worldly honors.
