What it comes down to is this: In the middle of a war, when the nation needed its very best, Kagan decided that gay politics was more important than the needs of the nation.
It’s that simple.
Gays know the military is different. They know that there are a million legitimate ways they can oppose discrimination in the civilian sector.
And yet they focused on attacking the military, and reducing its effectiveness.
The simple answer, again, is that these were left wing people that love to attack the military, no matter what the issue.
