Without wishing to make it the central issue, I would also like to point out that as an organization becomes more densely populated with doctors from the psych "sciences" fields, it tends to develop a center of gravity in opposition to firearms and liberty (as self-sufficiency) in general.
The more they focus on "PTSD" as the broad tar brush for returning vets (and, of course, anyone who's been injured), the more they're going to be, organizationally, firearms averse.
PTSD is the new crazy, and crazy disqualifies you from firearms ownership, so expect those fields with a vested interest in enforcing "social norms" to apply the label liberally.
I am entirely disinclined to support any organization that has a heavy population of psych doctors of any flavor, basically because it can be used, and is being used, to outflank the Constitutional guarantees.
