That's what "Politics is the Mindkiller" is all about; our inability to come to an agreement on political matters.

In a sense, but most would not agree. I think all would agree that motivated cognition on strongly held values makes for some of the mindkilling.

I agree with what I take as your basic point, that people have different preferences, and Friendliness, political or AI, will be a trade off between them. But, many here don't. In a sense, you and I believe they are mindkilled, but in a different way - structural commitment to an incorrect model that says there is One Right Answer. For you and I, that isn't the answer. Politics isn't about a search for truth, it's about assertion of preferences, trying to persuade some to do what you want them to do.
