I had a Somalian friend/acquaintance that frequented the gym I worked out in some years ago; he hated American blacks, railing against them as lazy shiftless and entitled. Sound familiar?
The American blacks tease and taunt them mercilessly for that. But as far as I know, there has been no violence yet.
And as for the white and Asian kids in the school...they just try to make it from class to class without getting involved in too much drama.
