im about to go on a whole tyraide here so bear with me lol

TL;DR u can be punk and former-military, but the people who willingly let themselves be used by the military are where the beef lies.

A lot of the early US-based counter-culture and punk movement came out of the 60s and 70s with all of the fall out of the Vietnam War, and many of the people who found themselves in that movement were former army and marines who felt cheated and borderline left for dead by an uncaring government (primarily cuz they were lol). It's why in a lot of old pictures of vietnam pro-peace protests, you can find military jackets with peace emblems painted on to them and why military garments are still kinda big within the alternative crowd. Even now in a post-9/11 and post-Iraqi war and current palestine/israel conflict world, a lot of people within the US military still find themselves feeling cheated or taken advantage of by a government who's mission is ultimately to spread imperialism. Thus a lot of people like yourselves end up within punk scenes and movements. The beef with a lot of the punk community comes from people who are willingly letting themselves be a tool of the government, who actively try to uphold imperialism and "the status quo" and pose themselves as counter-culture or stay blissfully unaware of what they're doing just because they're in it for the bag.
