I think you give them to much credit, I think they had a very narrow view of who, all men included aren't the number of signers of the declaration something like 1/3 didn't own slaves and two thirds did ,so I propose that the reason they didn't address the issues , was more economical for one, they weren't willing to throw them selves in to poverty for their ideals,and two they need to keep the colonists on their side, they were about to enter a war they couldn't win,without the colonists support, they also need to the document that declared them free from the British to try and lure Spain or France into the war. so they were willing to infringe on someones else's rights but for all the right reasons is what you're saying, I'd also like to bring up Jefferson who publicly supported freeing the slave, owned over 600, profited from them greatly,bought and sold them with regularity, and refused to free them at his death unlike Washington.. he played both sides against the middle, spoke of abolishing slavery I n public to keep support of the northern colonies who thought he would eventually, but refused to put this language in the document to keep support of the southern colonies. And as to my on personal thoughts of the document, alot of it's true intent has been perverted by the rulings of scotus along party lines, this is still the land of liberty and justice for all(All you can afford that is) after two day of arguing my position on education hasn't changed nor is it going to.
