meh, there's a reason we are a republic and not a true democracy. There are some things that need to be filtered. In reality if we go to war there really should not be a ton of arguing about it if we just set the bar so high as to what constitutes a need for war.
and yeah thats not how voting works
in the sense that voting as we know it routinely results in the exploitation and deaths of others yes, you're correct, that's not how voting works
it would be quite a shock to many if their votes actually had consequences. if a vote for a hawk like mccain meant that you yourself might actually have to fight and die for whatever the fug is so important in countries that pose no threat to your day to day life
look at how easy it is to refuse to participate in an illegal war:
"My conscience won't let me go shoot my brother, or some darker people, or some poor hungry people in the mud for big powerful America. And shoot them for what? They never called me ******, they never lynched me, they didn't put no dogs on me, they didn't rob me of my nationality, rape and kill my mother and father... Shoot them for what? How can I shoot them poor people? Just take me to jail."
