It makes as much sense as telling white people that they cant relate. I grew up in a very small town, out riding my bike one day I was about 7 when a car full of blacks pulled over drug me off my bike, threw it in the canal and then punched me for no reason... How can I relate. Fast forward to my 20's and driving threw Mississippi delta area, local cops 2 black officers pulled me over, asked for insurance and ID for no reason, they TOLD me I was lost and that I should get back on the interstate. I got the hint. So again how can I relate.
Relating is a lot to do intellectually, can you relate? Your so called friend, sees your whiteness as a bad thing (they way he has been programed to), I can relate to that too. Sucks don't it? All races commit racism.
