You know what, I'm not even going to wait for your reply. Have you even been accosted by a soldier in official capacity? I thought not. As I recall, violations of the "freedom of the press, freedom of speech, freedom to demonstrate" we hear about were (and continue to be) committed by CIVILIAN agencies (ATF, FBI, etc.). Ever heard of Posse Comitatus? Look it up.
And trample the flag? You can't be serious. The military is not perfect by any means -- it's run by imperfect people. But, at our roots we are AMERICANS (not the NFL, NBA, etc.) and it's OUR FLAG. You will never see a real soldier/sailor/marine/airman disrespect it in any way. Those who hold sentiment otherwise are the exception and, when the system works, they are separated like chaff. Again, imperfect, but at the core it is GOOD.
I won't spend another minute picking apart your misplaced argument. You feel how you feel. If you have served, I am sorry for whatever happened to you that made you perceive the Service the way you do. But, if you have not served, shut the fuck up and educate yourself.
