> We killed millions of people, not even a hundred years ago, but now we're the paragons of virtue?

I don't see how this was relevant in any way to the discussion. What happened 100 years ago should of course be considered in discussions and in the law-making process today and it should not be forgotten, so that it will not repeat. But it isn't fair to still judge people born in a country where some of their grand(grand)parents did bad things.
