My hope is that when these kids grow up (I think they're mostly young girls besotted with LMM's Hamilton) they do some research and discover that Jefferson isn't the jerk he's portrayed as in the show. He was actually a brilliant guy."
So I see a lot of this kind of discussion and would argue that there's a much different cause-and-effect relationship than the one you outlined. We all know Jefferson was a slaveholder, but people who get as angry as this didn't form this opinion based on his being a "jerk" in the show, but from reading more up on the real Jefferson. People tend to love his character, but these guys acknowledge that the real Jefferson was actually more unsavory than depicted. It isn't giving them credit to claim that they're angry just because he antagonized Lin as Hamilton; they're angry because he owned slaves, and because the power differential with Sally Hemings means that their relations probably couldn't have been consensual. Sally was also with him in France, where she could have been free if she petitioned, but agreed to return to Monticello and slavery on the condition that he make good on his promise to free her(/their) children when they turned 21 -- which he didn't. None of this is brought up in Hamilton; in fact, the small exchange between Jefferson and Sally is superficially amicable.
So maybe their disgust with him disregards his other accomplishments, but I wouldn't say it's unfounded. He was a brilliant guy but that's not a reason to praise him on sight. It's good that these young people, as you say, don't feel like these figures are beyond reproach, which I think is one of the seeds planted by the show. (While we're thinking about it, Columbus was pretty awful too, and he has a whole holiday.)
