Historically, the military has only been used to suppress free speech. Lincoln used the military to assault and imprison newspaper critics, as did Woodrow Wilson. FDR shifted that "duty" to the nascent FBI. Arguing that our constitutional rights would disappear if not for the military implies the US is under constant, external attack, which is demonstrably false.
LOL @ "spineless men", implying blindly following orders is courage, but the moral fortitude to examine orders is cowardly. That is the twisted logic of the militarist cult. It's sad really. I recently watched a documentary on the Winter War, where FDR (of all people) condemned the USSR for invading a tiny, harmless neighbor. Fast forward a half century and half the country somehow supports flying halfway across the world to occupy some craphole while demanding thanks for protecting the freedoms.
Sure is nice to be able to say whatever you want on the internet and not have the Gestapo kick your door down at 3am. Freedom of speech sure is nice isn't it? You're welcome.
