He makes a living as a public commentator on military affairs. It's not like he's minding his own business on a secluded beachfront condo, playing golf and reminiscing about the good old days. He's a public figure with an agenda. Being military myself, I know that his commentary influences people, and that affects me directly.
Beside's your comment makes no sense - would he be more authentic to you if he wore a wife beater and Lee's?
No, because his words and his appearance match. He dresses like a pompous, know-it-all elitist, and he talks like one too. So in that regard, a suit and tie, or jeans and a t-shirt, would be less authentic packaging.
It pains me to say it, too, because I've been a big fan of Hack for years. He really has lead a remarkable life. But in recent times he's run his reputation into the ground, and I'm only willing to overlook so much.
I am sorry - your off - dressing well is not a sign of elitisim. You panned Hack based on hs dress - God forbid he has a manicure too, eh?
