That letter is a shame to those six veterans. Disgraceful.
Young 17 and 18 year old kids are forced to make important life decisions about their future. Where to go to school (and what to study), where to work, or to enlist. Sometimes, these youngsters make the wrong decision and decide they want something else for their future. You see it with kids who change majors, who went to college, and decide they don't want the higher education or perhaps they can't afford it, and they drop out and work in trades, or maybe they enlist in the military. It is asking a lot of a teenager to make a major decision, have 4 years to figure it out, and then live the rest of their lives accordingly. There are going to be MANY who decide they want to take a different path while they still can.
How six individuals who have served (presumably honorably) can send that letter anonymously and try to shame a young adult for having a change of heart that will otherwise drastically shape their future, is quite shameful, in my opinion.
We are fortunate to have a period in our country where we have a volunteer military. It wasn't too long ago when we had a draft and any young man could receive a letter and be told to report to duty, life uprooted. And we are blessed to have vets who have defended, and active military who continue to defend, our liberties.
It sounds like these six individuals let their football fandom lose sight of that.
Shame on them.
