If it were WW2, then maybe you have a point. If it's Vietnam, Iraq 1 or 2, or any other modern conflict which is fought by poor people for the benefit of rich people, then they should NEVER feel guilty.
Would you die so some rich person can make an extra $100 million a year? Really?
If I were called upon to serve my country in any way, I certainly wouldn't dodge. I'd serve my country proudly. However, it's physically impossible for me to serve in the military. I'm not sure how drafts work in those cases, but I'm about 90% sure they only draft able-bodied people. I'd also like to point out that rich people can get drafted for either Iraq war, so claiming that only poor people can get drafted is ignorant(Military Selective Service Act).
Interestingly, there was a thread on here recently on John Wayne, and all the RWrs praising him to the hilt for being a 'true American hero.' He dodged the military: he didn't fight for his country or serve his country. This during WWII. Not a conscientious objector, just didn't go. Stayed home.
How is he different from Ali? Oh yeah, he's white.
