Here are my personal favorites of all time:
"I make no pretension to patriotism. So long as my voice can be heard on this or the other side of the Atlantic, I will hold up America to the lightning scorn of moral indignation. In doing this, I shall feel myself discharging the duty of a true patriot; for he is a lover of his country who rebukes and does not excuse its sins. It is righteousness that exalteth a nation while sin is a reproach to any people. " - Frederick Douglas - 09/24/1847
"Tyranny is Tyranny let it come from whom it may" - Protesters gathered in the Boston common after it was announced that the rich could dodge the draft by paying a poor man to take his place in the Revolutionary War
" While some people think that dissent is unpatriotic, I would argue that dissent is the highest form of Patriotism" - Howard Zinn
"Where we have reasons for what we believe, we have no need of faith; where we have no reasons, we have lost both our connection to the world and to one another." - Sam Harris
"Now, all we need is a little Energon... and a lot of luck." - Optimus Prime - Transformers- The Animated Movie - 1986
