But, I think that's the tricky part:

"And it's okay to praise Washington, Jackson, Franklin, etc for their part in founding and building the country and also condemn them for their wrongs."

How do you convince people that current portraits, monuments, etc aren't praising the good and bad OR (and I think this is much more the case) are praising the good and turning a blind eye to the bad?

It sounds like we need new portraits, monuments, etc to replace what we have currently.
