You told the GP how they should not act during dinner conversations, and double downed despite the GP telling you that you didn’t know how close they were. That comes off to me not respecting what they were telling you about their relationship, which is uncharitable in my book. Given my upvotes, I’m not the only one that feels that way.

Separately, plenty of good relationships can discuss politics without issue, and to not do so would leave the world only to their information bubbles.
