I hope you get to see the horror of war, then maybe you will stop with this total bullshit.
Before you ask, I have not served, but I have a close friend who did. He did not join during war time, he joined because he wanted to serve his country.
Let me tell you something, he is a shell of his former self. The shit he has seen and had to deal with I would not wish upon anybody.
Trying to compare the ghetto or "tough streets" to war is like trying to compare a small creek to the Mississippi river.
In closing, yeah we get your point that PTSD should not be a defense, but attacking people who have served makes you look like a 200% fucking dumbass that has zero understanding of real life.
