When you say that people who didn't run from the draft showed courage, you're insulting people who volunteered.
Whatever his actions, your extreme stance isn't the right approach. Regardless of your intent, your statement insults both drafted and enlisted. It implies that enlisted people feel they're superior to drafted men and that they feel insulted when drafted men take pride in serving when called upon. You're also saying drafted men shouldn't take pride in serving when called upon. While I cannot speak from experience, I doubt that enlisted vs drafted is their biggest concern during a war.
