No vote; post was at +2 and that seems appropriate to me.

Trolley problems have four weaknesses: true.

It's bad that trolley problems have weaknesses: sure, but you didn't propose an alternative way of forcing people to reason about thorny moral problems. Criticizing trolley problems without proposing an alternative is like criticizing liberal democracy without proposing an alternative -- easy, valid, and pointless.

Trolley thinking seeps into politics: highly unlikely; most people-thoughts about politics are had by people who remember nothing from any philosophy class they ever had. To the extent that people assume perfect information, deal in extremes, etc., it's because of generic human biases, and not because people's rationality is being hijacked by long exposure to trolley contemplation.

Biases in political thinking are bad: true, but trivial.
