@twistermind: It has been my experience that the VAST majority of people in the US have great respect for the military. There are however some folks (who typically although not exclusively are on the left) that do not like or care for military service.
They consider them worthless, call them criminals, or baby killers etc. By and large, folks appreciate our service men and women.
With any group there are always going to be outliers. Both good and bad. The military is all volunteer and comes from the general population so the challenges in the military usually closely resemble those in the civilian community but because we are small as an overall percentage of the population and because there are standards to get into the military, the problems aren't as pronounced.
I appreciate the acknowledgement but that isn't why I joined. I did it to see the world, serve my country, learn a job skill, and escape an impoverished area where I grew up.
