Re: Jeez, exactly how old are you?
Indeed.
But the atrocities referred to were committed by people long since dead and rotted.
There is absolutely no need to feel shame about what others did centuries or decades ago, regardless of whatever political entity whose name it was done in.
Let's just accept that bad things happened in the past, often by merely ignorant people, and move on.
Putting the shame of our ancestors onto ourselves is pointless.
Let us take the blame for our own mistakes, of which I am sure there are many.
