The people I rate highest were those who openly said they weren't going for moral reasons. Muhammed Ali couldn't fight for years because he had religious reasons the government refused to acknowledge. Others went to Canada or Sweden.

Next are people like Bill Clinton. Had a valid student deferment and talked about how bad the war was.

Further down are people who used legal means, but were silent.

Lowest are people like Bush Jr. who finagled his way into the National Guard [and bailed on his last year] and Trump who lied about his medical condition. Both of these two were happy to have other people die to defend their right to be a rich kid.
