Yes, without question, I would have risked everything.
What's the choice?
Risking, or explaining to your children why it's okay to look the other way when perfectly decent people......elderly, men, women, and children, are being carted off like cattle to be imprisoned, degraded, and likely killed?
It's wrong, but at least it's not happening to US.
This was very much a part of the problem. Fear drove people to look the other way and find reasons to justify it because at least it wasn't happening to THEM. Or, they believed it was the right thing to do to an entire race of people. I can't imagine trying to explain that to my children.
Irony can't be the correct word, but even people in the "death camps" were driven to turn on each other as a means of survival amongst themselves.
Survival.
To this day, some people aren't even comfortable hearing about the atrocities. To this day, some people even deny that it ever happened.
Anyway, this is a touchy subject for me for personal reasons.
You mentioned a book. I would like to suggest a few books as well, aside from the obvious...The Diary of Anne Frank.
1) Night - Elie Wiesel
2) Milkweed - Jerry Spinelli
3) Summer of My German Soldier - Bette Greene
4) The Boy In Striped Pajamas - John Boyne
My children have read all of these books. They aren't for the faint hearted, just to warn you.
My son's top pick is Milkweed.
