If the tables were turned, and a conservative bride excluded leftist Uncle Dave, I can almost guarantee the following would have happened:
1. Uncle Dave would melt down publicly and privately and doxx the bride.
2. The bride would feel vindicated in her decision, and enjoy her wedding.
3. Uncle Dave would inquire if he was missed at the wedding, and why hasn’t anyone asked about him not sending a gift.
4. The bride would reply “Uncle who?”
Put succinctly, this is the noxious bride telling her uncle, with the dingbat mother’s approval, “I hate your guts and you are not invited bc you are a Trump supporter but send your usual voluntary gift of $ 1000 anyway”. And he gave the correct answer, NO.
