I think what's uncharitable is assuming that someone is 'afraid to speak out' just because they don't want to wade into politics.

What a strange comment, the most uncharitable one I've read in a while on HN. I didn't pick up anything uncharitable at all in the comment you are complaining about, while yours reeks of it - and in the same breath publicly wishing everyone else were more charitable!

What was not charitable in simply suggesting an alternative explanation that did not involve fear of retribution? This is a friendly discussion (or so I thought).

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.
