it is always amazing and sad to see how far people will go in their denial of history...

like the guy who stood up in a session during the 2013 Republican convention ( please bear in mind that the Republican Party was the party of abolitionists and the session was presided by a black Republican on the issue of how to attract more American Blacks into the Republican Party) and asserted that it was absurd for American Blacks to be upset about the issue of slavery... they had it pretty good back then... free food and lodging. WTF?????

or those who insist that the Holocaust never happened...

I suspect that these people have such delicate egos that they must take their feelings of self worth from external sources, rather than being secure in their own value. They take their identity and self worth from the group they identify with... I'm American... white... black ... Christian... Muslim... the list goes on. They then perceive any less than glowing approval of that group as a direct attack upon themselves... how else to explain how personally they react to what I perceive as fairly neutral comments.

Facts are facts... take them and learn from them. Try to avoid repeating past mistakes... which you can't do if you can't acknowledge that mistakes were made.

Some useful links were posted and most of the posters have been reasonable, so there has been some value to this thread... but arguing with the wall is not very productive and has only served to demonstrate the lengths to which some will go to avoid altering their mindset.
