Am I being a bad daughter/ neice?

No, he was very wrong. He had a hidden agenda, looking to pick a political fight. He was extremely disrespectful, considering his age. Just because he is old does not mean he gets a free p when it becomes to being intentionally rude and offensive. I am an old fart I speak from experience. If anything, I know not to discuss hot on topics such as politics. I might not agree with the young, but I respect their views (to a degree). I am more than shocked he acted this way, sounds like he is just a jerk that grew old, and still is a jerk. Peace.
