Clearly, this article is just the white supremacists and their power structures writing puff pieces to hide the slavery lurking within the black heart of the Valley?
Take this anecdotal datum with a huge grain of salt, and season it further with the fact that I'm dredging up memories from ten years ago. Maybe it was Indians (yes, a subset of Asians, I realize), I don't know. I just remember asking HR about $NON_WHITE_GUY, and was told he didn't count because (paraphrasing) "successful minority group in software".
Nobody—I repeat, nobody at all—is claiming that "the Valley is dominated by racist white men who systematically exclude all outgroups." That's not a thing. Nobody's saying it, except you.
However, people are quite correctly and accurately pointing out that there is an underrepresentation of minority groups in tech. It's great the Asian tech workers aren't suffering from this - but that's not the only problem! In other words, the target of attack is not "white men", but underrepresentation of other groups!
Ignoring for the moment that this article is out-of-date, you'll see from the numbers contained in it that while Asian-American workers proliferate, a mere 4.2% of tech jobs are taken by Hispanics - despite this being a group that forms fully 25% of the population of the area. The same vastly disproportionate numbers apply to other groups. And that's without even getting started on the social and economic issues surrounding the fact that these are H1B workers.
There's no quick and easy solution to this problem, but your gross mischaracterisations do absolutely nothing to help.
