I support BLM and what they stand for. That being said, I saw some buzz on release day about this and started reading and watching YouTube interviews with the cast. Some of those cast members are activists and give thoughtful interviews on what it was like to play these people on stage. When I saw people accusing Lin of being a racist I shut it down and anything said after that has no validity to me. It's an outrageous accusation.
He doesn't glorify Hamilton. Just because it's called that and it's wildly popular doesn't mean it's a glorification of the man. He was a jerk and they portray him as such. I think many people who say such haven't even seen it.
Our founding fathers had problematic backgrounds in the institution of slavery. It's part of our history and it's not something that should be ignored. However, there are better ways to go about it than calling someone like Lin Manuel Miranda a racist and trying to get a Broadway show, which has almost an entire cast of people of color, canceled. Focus the attention on who really is racist and work to dismantle that from within our government.
