Had the target of the video in the OP been a white person, our natural response would have been to pass him off as "just another idiot," because white privilege shields him from having his poor behavior associated with his race. Blacks do not enjoy such privilege.
Flame me all you want, but as a white person myself, these are sordid truths that I have had to come to grips with (and still struggle to).
I don't want to flame you. I just disagree with some of your ideas.
I disagree with your idea that racist comments by white people are shrugged off as OK. Maybe fifty years ago, but not now.
As for your white guilt, I really hope you get over that. How is being white YOUR fault? If you're not guilty of racism, then you're not guilty - PERIOD.
If you are chosen for a job and you think it's because you're white, maybe you shouldn't take that job. Would you want to work for a company that's racist? However, before you act rashly, you may want to consider the possibility that you are the best qualified for the position. Most employers aren't stupid. Most employers want the most qualified person for the job.
I worked in the staffing industry for about 10 years in the American South. I did professional placement. I can count on one hand, with fingers left over, how many employers told me or hinted at me that race would be an issue in their hiring decision.
In fact, when I had a really sharp candidate that was a minority (Oh, wait, white, non Hispanics are the minority in Texas! But you know what I mean...), that person was nearly always placed very quickly. Most employers would LOVE to have a great employee who is a minority, since the EEOC is so prevalent and demands such racial diversity in the workplace.
Qualified is qualified. Poor work ethic is poor work ethic. Fair is fair. Racist is racist.
I judge people, not by the color of their skin, but by the content of their character.
