It is unfortunate that geography meant that everyone arrived home on the West Coast and were subjected to its cesspool. Bad enough to go to war, then to be treated like that.
I never saw anything like that in Texas. In Fort Worth when I was in high school we sent care packages to units in Viet Nam. I was in college in San Antonio 67-71 and the boot medics from Fort Sam and the Lackland kids were all over downtown tourist attractions and treated with full respect.
