You are trying to process what happened.
If someone threatens me with information, my first instinct would be gather information about the other person, to see what can be weaponized against them, if I feel the need to protect myself. Which doesn’t mean that I plan on retaliating, but I want to be prepared in case I feel I have to.
That being said, you said that sharing information might have been malicious or it might have been a case of bad judgment. The first step is in figuring out which one it is, or if there are any other options in the range of explanations, before planning a response.
For all my posting that others find problematic, it’s not that I am unaware that participating in political discussion can have real-world repercussions. I’m not being careless. It’s not necessarily that I believe WAAF, but I think we’ve reached a point where there is no going back to some sort of pre-Trump civility. There’s no moving forward without passing through some sort of transitional period of conflict. Not necessarily civil war, but not some peaceful change where a bunch of people realize that they have been racist butt-heads and repent. And I don’t shy away from the idea that civil war is in the range of possible outcomes.
So much of all of our decisions are rationalization and bullshit.
This is an idea worth exploring. I do come back a lot to consequentialist vs deontological reasoning. I think most people decide their preferred outcome and work backwards to find a path that lets them arrive at that outcome. I am much more willing to focus on the decision-making process and accept what ever consequences are output by that process. I may go a bit overboard in highlighting spots where I am willing to accept undesirable consequences as a way of proving a point.
Given the poker-related genesis of this forum, we can talk about results-oriented thinking and concepts like Sklansky bucks. I’ve internalized the idea of not being results-oriented, so it might be reasonable to say that I evaluate politics in terms of how it affects theoretical lives rather than how it affects actual lives. And I can see how that perspective will rub some people the wrong way, how it might come across as lacking in empathy, or even sociopathic.
In determining how to resolve your personal situation, it is possible that you see tension between how you think you should act and what you think will actually happen if you act that way. It would be natural to want to adopt a more risk-averse strategy because we are talking about a single case.
