Sometimes you’re forced to go to extreme measures to get past the moral of the story. Scorsese created Gangs of New York to show us that we’ve always had a problem with immigrants and we’ve always been wrong. The way Trump talks about the Mexicans today is the same way Bill the Butcher talked about the Irish back in the 1850s. What Marty doesn’t get is that they’re both right. The Irish were a complete mess when they came here and they turned New York into a hellhole. The Mexican experience is very similar, especially when you’re able to gather real statistics about the number of rapes that occur during border crossings and the giant surges in crime.
