I think one should, in most cases, not mix the questions of morality and choice.

Nothing is to gain from mixing the question whether something is morally right and whether it is a choice.

Being gay is not a choice, but even if it was, it still would not be wrong to be gay. Shifting the debate to whether
it is a choice or not, when one really wants to debate whether it is moral or not, IMO is not helpful.

I, personally, think the United States military is an organization with no morals and has been that way for decades.
I think there is nothing remotely noble or heroic about joining this organization.
However, I understand that most people are driven to join it by forces largely beyond their control. Two seperate issues.
