(I'm a white educated middle-class man myself, and a career in the tech world has been easy and natural for me. I'd love to believe it's because I'm really that good, but I try to be aware of my privilege.)
Dunno about all of that ... I myself am not sufficently race obsessed I guess. What I meant was that in most cases people get ahead for reasons that have little to nothing to do with merit, and in my experience also that have little to nothing to do with race.
Maybe if you find yourself constantly surrounded by racists you should evaluate how your choices contribute to this. I don't have this experience.
And I'm pretty sure there would be some legal implications for what you claim, so if you are aware of this and not reporting it I'm pretty sure you face potential legal liabilities.
I think it is pretty disgusting that people just look the other way while they witness racism. If I ever saw anything at my place of work that would suggest any racism in hiring choices the person would not make it to the end of the day.
