Ludicrous perspective.
I literally live here. In an area that is seeing some of the most diversity and a ton of immigrants, I work in a kitchen and have worked with people from all over the world from Thailand to Senegal, Venezuela to Iran, India to Australia.
I've had this conversation of American and racism for literally decades in my life of working with these people both having to inform them of inappropriate actions and just general discussions. There are communities from all over the world here.
A huge reason people think the US is racist is because they watch the media and think our constant conversation of race suggests it's a huge fucking issue. Most countries do not have the diversity our government has shown and the rise in racism in the US is because of this bullshit fear of "rEpLaCemEnt thEoRy" from the growing diversity.
Every country has racism, most don't talk about it especially at a level where their government has constant calls to face the music about it.
