I'm an American of German ancestry.
After my grandparents death I inherited their property. They had always been stellar grandparents to me. I loved them.
Searching through their belongings I discovered a trunk. It was heavy and it was hard to unlock. I finally got it open and there was anti Semetic N*** literature there in English and German.
My family doesn't share their anti Jewish feelings and neither do I. This was an unpleasant startling revelation about two people I had loved dearly when they were alive.
