This is like blaming someone for something that their ancestors did, that they had no involvement with and didn't condone anyhow. I'm pretty sure, most Americans have had someone in their family do something really fucking stupid or horrible, yet we don't blame them for it.
Your father signed off on the massacre, rape, and starvation of over 100,000 Palestinians, does your PR team have a really cool Marvel quip lined up for that one too?
