I fail to see the problem, this is people, who have a good chance that their grandparents wasn't born when the Holocaust happened.
Fits me. My moms parents were born around 1933/35, and were kids during the war.
My dad's dad was born 1925, was eight years old when Hitler was elected, and had to spend his best years somewhere in Russia (from which he never, ever recovered, mentally).
Nevertheless, it is our, the Germans, damn duty to live with what happened and tell the later generations. Has nothing to do with guilt, but with responsibility.
