I'm your garden-variety liberal who works at a tech company and the description here is entirely foreign to me. I've mostly worked outside of tech and my social circle outside of work is almost entirely liberal but non-tech - the tech world is far more progressive, the culture is far more supportive in general and more specifically in the direction that is favorable to outsiders and marginalized minorities. Outside of my tech social circle, it's extremely common to hear casually racist and sexist remarks that would get you either fired or ostracized at tech companies. And that's before you get to heteronormativity that is endemic in mainstream society but is frowned upon at most tech companies. The sensitivity towards transgender people is also mostly non-existent in non-tech, non-elite mainstream society, even among liberals.
Maybe Valerie Aurora can find places that are more supportive than tech, but the median work environment in the US is full of Trump supporters and can be outwardly misogynistic, racist and transphobic. The myopia here among people who have rarely experienced the life outside the bubble is quite concerning.
