Even when I know that outside of the US, most of us have the same opinions on what the trump admin is doing (especially in the pen and paper RPG community, where not being transphobic is basically a requirement), I still hate comments and discussions about it, probably for the same reason than the author does.
I disagree with his axis though, I've read a lot, and I mean _a lot_ of books and the more I read, the more left I went. And I started almost tea-party libertarian, then liberal-libertarian (because logic, and my class) then I understood power and class and became original libertarian (think Emma Goldman).
But politics are much more than that, it's how society organize, and if you can't talk to everybody about your city evicting the parasites who mismanaged and eventually brought down the waterlines because you're afraid of 'groupthink', you are fucked.
