Utah, LDS central, is right on the other side of Nevada from California, and California and the Bay Area is the nearest interesting/fun place for those fleeing SLC.
It makes sense.
That makes them about as rare as Eastern Orthodox, who I rarely hear anything about, half as common as Hindus, ten times less common than Evangelical Protestants in San Francisco... I think it's fair to say that HN has a minor obsession with Mormons that cannot be explained merely by their prevalence in Silicon Valley.
(For what it's worth, I am an atheist and have no Mormons in my family.)
If you want to see HN address Muslim issues in the US, search “Sharia”.
Not being American myself, my hunch is that the Mormons in CA might be well established, subsocieties with long traditions. And the Muslim people might have more of single first-generation immigrants.
The author is discussing the impact a society/institute can have on an individuals choices later in life through the lens of their experience within Mormonism. They never attempt to gatekeep that it’s a unique thing Mormons go through. Ultimately she discusses a topic that encompasses all STEM industries at the moment, which is equal opportunity and free choice. As a result I’d argue it’s very topical for HN irrespective of the religion.
