In my effort to understand more of what's going on in American life and politics since last year's presidential election, I've started listening to various American podcasts (I listen to British ones too; it's while listening to podcasts that I get a few rows of complicated knitting done of a sweater I started... um... several years ago. Back and front now done. Onto a sleeve). One I enjoy for its variability is Federalist Radio Hour. Today they are talking about bro culture, something I'd never heard of before. Some of it is really funny.

Always smacked of The Third Reich to me.
