I want to live in a world where *everything* that makes me uncomfortable or might cause pain or conflict is excised from history. After all, if it never happened, no one can be pissed off about it--and we can all get along fine. No more racial resentment, no more ethnic conflicts, no more religious wars. We get along, we always got along, end of story. Israel and Palestine always co-existed in peace beside each other. Europeans, Africans, and Asians discovered the New world together and have lived here peacefully together ever since. Every religion is the religion of peace and always has been. "Genocide" is just an abstract concept used by fiction writers, not something that has ever happened in the real world.
Laugh if you want, but wouldn't that make for a much better world? Why focus on the pain and resentment when we can reinvent ourselves as something much better?
Sure it all involves a good dose of self-delusion, but a lot of people have improved their lives greatly with a little self-delusion. After all, no one starts down their path to self-improvement by admitting to themselves that they are an unexceptional, not particularly good or worthwhile person. They start by telling themselves "I am a good person, I can do better" even if they know deep-down that they're lying to themselves. And, quite often, the lie actually BECOMES the reality. Convincing yourself that you're a better person can actually MAKE you better. Why not apply the same principle to society as a whole?
I'm not being a troll here, I'm asking a serious question. Wouldn't we be better off for it?
Because to forget our history will lead it to repeat itself, human nature will ensure it.
