On the Fact that We Actually Live in a World Now in Which, "I'm White but I Identify as Black", Is Taken Not with a Grain of Salt but Seriously

I guess that they just weren't down with all of that "white privilege".......And how far can we take this shit? I mean, can I go down to the avenue tomorrow and scream, "Stella, Stella!!", and when the coppers come over to me I can tell 'em, "Yes, I'm Will Hart but I identify with Stanley Kowalski"? Please, please, give me some parameters here.
