Since we're going with anecdotal evidence here: My wife worked at a start up in SV that had a 'management' consultant agency come in and set up cult-like team building events, where employees would shame someone up on stage in front of each other. Predictably, people were brought to tears. My wife was threatened to be fired (and lose her work visa) when she walked out and refused to participate. She and a couple others were lucky to find new jobs quickly, but not everyone could. The startup has since stopped the events because they were sued.
Just because you don't personally experience it doesn't mean that it's not happening. If there is data to show that people are being marginalized in the bay area, then odds are it's happening even if you haven't seen it yourself.
