Uhh no.
I mean it is literally about Haitians though, as the city of Springfield Ohio already had been incentivizing cheap import labor to take over for the American labor that had left and wouldn't work for low wages.
Literally, a guaranteed work status and easy entry because of destabilizing forces in Haiti has meant a huge influx to the point that now more than 1 in 4 residents in Springfield are in fact Haitian.
It doesn't mean that outlandish stories to create fear and tension are a good idea but just casually changing the details to say it's about black people is you also trying to push a narrative on a struggling city with many real issues that are its own.
