You are probably going to get simular experience of being exposed to those of different color/background also in college or on job. We live in a very multicultural society unless you are one of few way back in the boonies.
As to draft, it is, and always was a bad idea in a country that claims to be free. When you get down to it you are in effect forcing an individual to do your bidding by threatening imprisionment/death. In other words indentured servitude for an individual who has not committed any crime. As that individual selected out, If you are morally opposed to the action being fought, then you are placed between a rock and a hard place. Do you run, do you go to prison as a martyr, or do you kill for a cause you are opposed to?
In a free country, going strictly volunteer means there is always that final power check on the system. In a war to really trully defend your country and your family, you wont have any shortage of volunteers. On other hand in a war for cynical money grabbing purposes or leaders' ego purposes, the citizenry will make their disdain known by not volunteering. Really trully I dont think the population as a whole are stupid, they will know when a cause is worthwhile and act more responsibly than bought and paid for politicians. I frankly fear my own government more than any foreign power and dont wish them to have the power to make me into a slave for rich contributors.
