I dunno. At least one pacifist won the MoH in WWII. He was a Seventh Day Adventist who was drafted, and because of his religious views was made an Army medic (so he didn't have to "take up arms"). He still placed his life on the line for his people.
Methinks you are conflating "pacifist" with "coward." The two are not synonymous.
I'll concede you one example.
We will just have to agree to disagree.
