As a white guy, I never had to deal with profiling. Except when I wear a hoodie and people assume I’m a hipster rather than just a chilly dude.
Here’s a fun tip if you happen to be armed and live in a “Stand Your Ground” state: If you let the unarmed dude who scares you know you have a gun instead of shooting him right away, he’ll probably stop doing whatever it is scaring you. Unless the thing he’s doing is simply being black. People can’t stop doing that.
