But then you've already lapsed into consequentialism, and thus stuck yourself with a mandate to consider the trade-offs between desirable and undesirable consequences.
Yes, and deontologists and virtue ethicists consider trade offs between different principles or virtues.
This is not what deontological and virtue-theoretic politicians actually do.
This is not what consequentialists actually do either. In particular, I've never seen an actual utility function, much less using one to compute trade-offs.
"Look how morally brave I am for being willing to let this sort of thing happen out of pure principle!"
Well, this is also what consequentialists talking about trolley problems sound like.
Well, this is also what consequentialists talking about trolley problems sound like.
Disagreed. The correct consequentialist answer to a real-life trolley problem is to Take a Third Option and not sacrifice any lives, every time. If you find yourself stuck in a perverse situation, then yes, you pull the lever, not because it's a good thing and you're being brave, but because it's the least-bad thing available in your perverse situation invented by philosophers who like perverse situations.

Of course, with the prompting to state my own thoughts, I simply had to go and start typing them out. The following contains obvious traces of my own political leanings and philosophy (in short summary: if "Cthulhu only swims left", then I AM CTHULHU... at least until someone explains to me what a Great Old One is doing out of R'lyeh and in West Coast-flavored American politics), but those traces should be taken as evidence of what I believe rather than statements about it.
Because what I was actually trying to talk about, is rationality in politics. Because in fact, while it is hard, while it is spiders, all the normal techniques work on it. There is only one real Cardinal Sin of Attempting to be Rational in Politics, and it is the following argument, stated in generic form that I might capture it from the ether and bury it: "You only believe what you believe for political reasons!" It does not matter if those "reasons" are signaling, privilege, hegemony, or having an invisible devil on your shoulder whispering into your bloody ear: to impugn someone else's epistemology entirely at the meta-level without saying a thing against their object-level claims is anti-epistemology.
Now, on to the ranting! The following are more-or-less a semi-random collection of tips I vomited out for trying to deal with politics rationally. I hope they help. This is a Discussion post because Mark said that might be a good idea.
