tell me how her quote is racist, in your own words.
To be honest I wasn't going to carry this pointless discussion on with you but being as I'm bored I'll amuse myself slightly. She's saying that "anything is possible" for Caucasian folk on the phone because of the way they sound. Although that comment makes zero sense as accents are all different it's still singling out a certain race. Again if it was a Caucasian person saying it about another race that would be racism but because it's a black gal saying about Caucasian folk nobody bats a eyelid. You denying it's racism is just proving my point really.
You do realize you're speaking to the "white sounding black chick" right? Check your privilege bro
