Having served or not having served in the military is not the measure of a person.
I have served my country in different ways. Todd no doubt did as well. One thing we learned, which you evidently didn't, was to respect our country and abhor traitors.
Todd is not obligated to disclose any details of his life to anyone--and especially not YOU. You might use that info to harass him in any one of a number of sick ways. At the very least, you just want to use that information to insult him. He can and should tell you to piss off.
