I get most of the sentiment here, I really do. The world is vast and people are small, and there are just not that many people of whom you can say the world is a worse place because of them, but yeah, Dick Cheney's on that list. He's not Bill Kristol, whose moral standards and ethics have always been clear, but those standards lead to good or bad outcomes depending on the rest of the world; nor is he George W. Bush, who could have been a good man but was, fatally, weak.
But this brings me back to a question and a concern I've had since the good old days when I was on the inside of some conservative circles: do people on the right actually believe the things they say? So you have, among things I've seen, on the one hand, Bill Kristol in a conservatives-only conference defending no-fault divorce and gay rights. Pretty clear that he believes that one.
But I have also seen prominent conservative intellectuals joking before a talk about how they're going to put on a performance to meet the crowd's expectation, which didn't seem to be consistent with their reflective judgment--i.e., they were going to complain about an academic work that they actually thought was either good or acceptable within academic standards. Pretty clear he didn't believe that one, or not entirely. However, I was in the room when the same person endorsed, unprompted and at some length, the "homosexuals infiltrated Catholic seminaries in the 60s and 70s to bring down the church" theory.
And there are some more cases like that, in my experience: sometimes it's putting on a show for a "conservative" view to a mixed or liberal-leaning audience; sometimes it's kayfabe for a supportive audience, in the "we gotta pretend like every Republican candidate is a good one" sense; sometimes it's a deeply held belief. I think all of the people I've known in this category know whether they believe the things they're saying or not, but it can be terrifyingly unclear.
And look, I'm no longer an academic, I don't need to keep to a neutral pose. I'll save my interpretive energy for things along the lines of "why do Herta Müller's books all have great, exciting premises and terrible execution?" I've come around to the view that it's the words out of your mouth that matter, and your actions, and it's not worth the energy to figure out if you mean it or not.
This is of course reductive and opens me up to exploitation, but here's another thing I've learned in my time as an HR person: the racist who wishes to act on it will eventually tell you they're racist. You might think that's an insane thing to do in front of your HR rep, and it is, so much the worse for those people, but the people who think they're being clever and putting one over on you will eventually need to make sure someone knows what clever people they are. So the odds are pretty good over a long enough period of time that someone will reveal their real thoughts and beliefs. Especially now, when there seem to be so few sanctions for being an awful person with awful beliefs.
