Maybe, maybe not...but either way, it wasn't R.E. Lee's call, was it?
Perhaps not. But as you say, you're opposed to abortion: consider a weird hypothetical. The UN declares abortion to be illegal, world-wide. Would you not only defend the US but lead the military in an aggressive war against the UN based on this one policy?
(The analogy is readily admitted to be a bit lame...)
Lee could easily have led the *US* forces, which would have been far better for both the US *and* Virginia... and his own soul.
Forced to agree here.
