Jessie Jackson called New York City "Hymie Town". Really derailed his "career" there. Mel Gibson beat his girlfriend, and has bashed Jews, gays, and Hispanics and it has hurt his career exactly zero. He's about to become a billionaire.
1. Entertainment industries (sports, TV, movies, etc) are NOT equivalent to normal everyday life in a "regular" job.
2. White guilt is so high these days that people like Paula Deen are being destroyed by things they said 20 years ago.
3. Donald Sterling. (Although if idiot people would have just not freaked out and let him die, he wouldn't have profited from it).
You sound really paranoid. Sorry the man is keeping you down so hard.
