racism against blacks is still a deeply institutionalized practice in this country. so boo hoo, some lime - sorry - brits got yelled at - probably the only racially-motivated pickle they'll ever be in in their entire lives; but it doesn't make it right. The fact that they are white and can travel abroad for school puts them way ahead of most of the people who they were housed with.
so yeah, racism works both ways just like Mike Tyson beating on a 7 year old's a fair fight. I'm sure that kid can throw a punch - just like any black person can legitimately be a racist.
