he's not having a moment though, this is just what he believes, as far as I can tell. And he's saying this not as someone who fought for better urbanism and failed, but from Amsterdam, as someone with a cushy job and the ability to move wherever he wanted who just left and didn't fight. And that's not to say he's wrong. US/Canada are not particularly responsive to pressure on this issue, but he's also only considering the activism of going to council meetings and putting up yard signs, and maybe in the extreme case a little rally outside city hall, he's not considering urbanism as part of a socialist movement that goes beyond petitioning the liberal government.
