Especially black people...is she right or am I right?

I understand completely. I agree with you and truthfully there is a degree where cultural differences enter in and then there is a point where rude, disrespectful, inappropriate behavior is just that. I have found that there are often tremendous differences when it comes to African immigrants to America and Black Americans & I struggle with this every day. One can not help but wonder if by "stuck up Africans" they really mean someone with self respect and morals. As Ogun stated in his reply, "this hurts our society", & I pray for the day more people realize this. YOU are right and please dear sister, never let anyone convince you otherwise. I wish you all of the best.
