You are not wrong. Reading what you typed, I can’t help but think about the people who have spent so much time defending their self-serving opinions that they can no longer have any reaction other than to start arguing. My ex had a bad case of bi-polar. She was really a great person, but any time someone disagreed with her (or even if she thought they were disagreeing) a switch would flip and she would rage at you until she thought she had won. Even walking away wasn’t enough because then she wanted an admission that she was right. Funny thing was that after that had passed and she calmed down, you could talk to her rationally and she could see your point, but it simply wasn’t worth the effort.
