Nat Eliason wrote this essay. If you are a Medium subscriber, you can applaud for it here. A random excerpt:

You might say “but I don’t want to read political philosophy.” That’s fine, but then don’t pretend that you’re interested in politics. If you want to watch the news but you don’t want to read some John Rawls, then you don’t actually care about politics: you just like feeling outraged and talking to your friends about how stupid/brilliant Trump is.

Another random excerpt:

Emotional reactions to an idea indicate that you have a Level 1 or Level 2 ideology around that idea. If you feel any emotional pull to defend Democrats / Republicans / College / Christianity / Bitcoin / Crossfit / New Gender Pronouns / Income Inequality in the face of new information, that’s a sign that you’re at Level 1 or Level 2 thinking.

I had a positive emotional reaction to the essay. So perhaps I have not reached Level 3 in thinking about it.
