The biggest-mouth vets (think all the assholes in Congress, R or D) were probably the biggest asskissers and useful idiots during their service. They're rewarded and used as govt/media mouthpieces afterward. So there's nothing liberal about any of these wads, they're just slaves to groupthink. And because conformity is basically canonized in the MIL, they think the groupthink is righteous.
Why do all the spamfaggots think they're so speeshul?
