Without conscription there is no way that the Allies win WWII...
I'm more than ok with Hitler, Mussolini and the Japanese being defeated by armies largely made up of conscripts. Sometimes what is neccessary, isn't always "nice".
That happened a long time ago. Different people, different weapons, different cultures. People were more willing to sacrifice themsleves back then, and war required less skills and training than it does now.
Now, when we have women in positions of power and with more rights than men, why would young men sacrifice themselves to defend the country and protect the privileged class?
