You guys have to remember that almost everyone in the world in the late 1700s believed in slavery. It was normal and part of life. If you're going to hold slavery against the Founders then you might as well say everything that happened before 1865 counts for nothing. That every good idea before 1865 has to be dismissed because most of the world agreed with slavery, or at least before 1808 when Britain ended it.

This is simply anachronistic thinking, judging the past by the way we think today. Then what happens in 100 or 200 years when people in the future don't think like we do today? Maybe they'll think everything we believe in today is wrong and should also be dismissed.
