Indeed we should learn our history. What Thomas Jefferson had to say on the subject:
"god forbid we should ever be 20 years without such a rebellion. the people cannot be all, & always, well informed. the part which is wrong will be discontented in proportion to the importance of the facts they misconceive; if they remain quiet under such misconceptions it is a lethargy, the forerunner of death to the public liberty. we have had 13. states independant 11. years. there has been one rebellion. that comes to one rebellion in a century & a half for each state. what country before ever existed a century & half without a rebellion? & what country can preserve it's liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance?"
Letter to Wm Smith, 11/13/1787
We should always be trying to correct injustice and form a more perfect union.
