Everyone’s anti-war until the war propaganda starts. Nobody thinks of themselves as a warmonger, but then the spin machine gets going and before you know it they’re spouting the slogans they’ve been programmed to spout and waving the flags the flags they’ve been programmed to wave and consenting to whatever the imperial war machine wants in that moment.
Virtually everyone will tell you they love peace and hate war when asked; war is the very worst thing in the world, and no healthy person relishes the thought of it. But when the rubber meets the road and it’s time to oppose war and push for peace, those who’d previously proclaimed themselves “anti-war” are on the other side screaming for more weapons to be poured into a proxy war that their government deliberately provoked.
This is because the theory of being anti-war is very different from the practice. In theory people are just opposed to the idea of exploding other people for no good reason. In practice they’re always hit with a very intense barrage of media messaging giving them what look like very good reasons why those people need exploding.
