Welcome to the world of acknowledging Racial and Social injustice. It's super awesome you care now and you want to participate in ending systemic Racism. There's plenty of room on the bandwagon and we're glad you've decided to jump on.
Just a friendly reminder, don't be a hypocrite.
You can't disavow historical figures for being Racists while wearing a Disney T-shirt. Walt Disney was as racist as be was antisemitic and misogynistic, which is a LOT. It's great you want to rename building that honor Racist historical figures! After you change Jefferson and Washington, make sure you change the name on Disneyland.
