Believe me, I think everyone ought to serve, as I did (2 years active, 6 reserve). What I object to, conceptually, is coerced service. The society whose members are unwilling to defend it does not deserve to stand against its enemies. That's why I like the idea of using military or equivilent national service as a qualification for full citizenship rights.
Your other post re Jefferson, Adams and Franklin is not apposite. In their time, there were other limitations on the franchise that ensured that only those with a significant stake in society voted. Each of them, as signers of the Declaration of Independence, placed their lives and property in peril for the sake of the country every bit as surely as if they had led regiments in the Continental Line. The point of using military or other service as a qualification is to ensure that each person who votes has demonstrated his or her willingness to place his or her life and property on the line for the country.
A universal draft would be more acceptable if our damn schools would teach just what civic duty consists of instead of teaching what one can get from the system.
I'm totally for the franchise being only invested in literate property owners, as originally conceived by those wiser than the courts that declared otherwise.
In Liberty.
