Most military veterans claim to have "fought for my freedom." Many claim to still stand ready to defend it today, and the current (late 2019) dispute over firearm freedom in Virginia includes a lot of veterans who say they're ready to fight for freedom there.
However, I must question their sincerity. In my experience, most former soldiers still revere political authority and chains of command. They believe in following orders first, and thinking about them never. This is what military basic training in boot camp is for, after all. As tax feeders past and present, they do not question the legitimacy of taxation. Sure, they're more likely than not to be decent on the subject of firearms, but liberty as a whole is foreign to military culture. While there are individual exceptions, I cannot support the conservative instinct to trust the troops as allies. I hear soldiers and veterans praising prohibition and militarized national borders. It was troops who shot students at Ohio State. It was troops who helped confiscated guns and evict people after Hurricane Katrina. It was troops who engaged in blatantly unconstitutional and immoral wars and committed atrocities from at least Vietnam through the present day.
They fought for the greatest threat to freedom in history: state monopoly. It isn't freedom the veterans espouse, it's a slightly expanded list of permissions. That isn't freedom.
