Had a black boyfriend once, and must say, that according to him a lot of his problems were due to his colour.
Him losing a job had never anything to do with his constantly being late.
People not liking him were always racist, not just fed up with his big mouth and arrogance.
If a cab did not stop for him, it was because he was black, not because the driver maybe did not see him, was in a hurry, had somewhere else to go, was off duty, or whatnot!
Also his brother for many years was very rude towards me, since he did not like a 'white' woman in the family.
(and all they do is talk about whilte racists)
So I don't deny that racism exists, I think it is also often used as an excuse to cover up ones own faults.
