You apparently aren't familiar with the production? Have you heard of Lin-Manuel Miranda?
Your historical recollection is a bit skewed. Hamilton's father was Scottish. He was born (out of wedlock) to a "West Indian" mother. That was 18th Century doublespeak for Black Lady.
Point Alpo. I was not aware of that. However your blackface comment was out of line. Nobody was calling for whites to play black parts and you know it.
