The price of liberty has always been high. Many, many Americans have given their lives for it.
But, the important thing here is that I wanted to acknowledge your courage in stating your views about slavery. As I pointed out in post 777, there are still a few people out there who are having trouble summoning up the courage to offer an opinion about slavery.
Good for you! ;-)
You are overlooking the fact that the war was started to suppress Liberty, not achieve it. That it eventually (several years later) had that consequence for a previously subjugated portion of the population is irrelevant to the actual purpose for which it was fought.
It has had the effect of increasing the subjugation of everyone else.
