I've seen that kind of thinking in the past and it's pretty popular view. I'm just not so sure about this moral aspect.
Why do you think it's more moral/ethical to abstain of supporting military? Maybe you won't do this but be sure that in some other country some similarly talented people will.
If you (and many others) abstain from it on similar basis you and closest people you know may be in danger of being affected by more advanced military equipment other (possibly hostile) armies can get.
Maybe it's just not in people heads that world and homeland safety is not given for free and granted forever.
