It’s a great song but an awful message. like most of the beatles politics when brought up it’s literally just is “pacifism good” and nothing much beyond that. There’s a real sense of naivety to it, no John, everything isn’t “gonna be alright” if we just loved each other. Things actually have to be done about the awful living conditions people are forced into and pacifism is only going to get you so far when dealing with those who impose said conditions.
