"Patriotic" is reaching.
I think it would be scarier if the US Gov (a uniformed Marine, for example) were to make public statements on 9/11 conspiracies, among many other questionable topics. Last I checked, this wasn't a Banana Republic where we have military coups.
If it were a private fb post, or by a simple college student, I defend the right. In this case... Move along, nothing to see here.
