It should be a source of shame that for centuries we lionized the exploits of explorers who sought only wealth and glory; murdering, raping and enslaving as they pleased. Even their own priests reviled their depravity.
A free and proud people should be able to teach their children the truth; that we can and must enact justice in spite of our history, not because of it. We should not have to fall back on mythology to spare our sensibilities. We do not need to celebrate how got here in order to be proud of who we are.
