Maybe you can give me a history lesson. Certainly they weren't angels and, as is the case of Jefferson, some probably didn't go out of their way to promote abolishment of slavery. But am I imagining things when I say that they put in place a system of governance and rule of law for freedom and equality that ultimately led to abolition of slavery? Isn't that what we are celebrating with memorials of them? What are we celebrating with a memorial of Lee? Killing blacks and fellow whites to sustain slavery and white rule? Don't you think there's some difference there? Now if we follow your train of thought, why are there so many memorials and monuments to Christian faith? Isn't that religion responsible for more horrendous deaths and horrific acts than any other?
