Zie grew up in CS, but was queer, and CS (at least back then) was very anti-LGBT. Principia, the CS university, would expel openly gay students and fire openly gay professors, and zir parents were homophobic too. The mom would listen to testimonials of people's "healings" of their same-sex attraction.

That made zir not fit in, and accelerated zir dropping out of CS and discovering the LGBT community, and non-binary identity.
