"If someone stomped on my flag, I would stomp on their head" and I have communication issues? Hmmmm
You may have macho dogma issues bud. Take the testosterone down a notch and try speaking to people and understanding their background. The military is not a political mouth piece, it is a trigger piece and a function of politics. The military do not make nationalist or political statements, they defend on political orders. The military don't also make judgment calls, they make strategic calls. Meaning the opinion of a soldier is that of his superior commander.
They are not trained or paid to think about why they are doing something, they are just told to do it, and given a pep talk for the sake of unit moral (as a strategic device).
So when a violent current or ex solider spouts off in ignorance, he needs reminding he is not respected for his opinion, but rather his following of orders.
