I don’t think anybody’s calling them perfect men, but you don’t have to be perfect to be great. Ya a lot owned slaves and while that was normal at the time it also isn’t ok for obvious reasons.

These were all ideas our founding father wanted to use for America and not their own flaws like slavery, native genocide, etc
