My wife is a vet. My dad was a vet. My step dad is a vet. All of my grandfathers and great grandfathers who were US citizens at the time of relevant conflicts were vets. I have uncles and cousins who were vets. The only reason I never served is because the government denied me for medical reasons each time I tried to enlist. It's a family thing. Many of my relatives or friends of the family have been injured or mistreated while in service, and many of those have been mistreated or neglected once they leave service. I've seen people denied aid after losing a limb in combat. Denied mental health care. Denied further VA assistance because they consulted with the wrong doctor. Have their GI taken away because they filed paperwork incorrectly. It's a long list. I've also had to live through a few of them killing themselves. I've seen this my whole life from multiple directions growing up partly on base and in the real world since. And, yet, I still love my country. I still respect the military and the people who serve in it. I'm also somehow still surprised by every new occurrence of this sort of thing happening to those same men and women.
After reading a bit, I see no reason not to sign.
