If you're surrounded by people who call trans people by their deadnames, you're most likely in a hate group. But a possible alternate explanation is that you're in academia. And it's not because that many academics are openly transphobic -- they just don't know that the site they fully trust, Google Scholar, is telling them to do it.
Google Scholar was developed in 2004 and has changed very little since then. It supplanted a lot of hard-to-use library search indices by providing a Google-style interface with a single search box. Now it's the most name-recognized site for searching for almost any paper by almost anyone. One aspect of the design was, authors are just a kind of search term. An author is a cluster of different ways to abbreviate a name, like Firstname Lastname, Firstname M. Lastname, and F Lastname, and you might see different forms in different places, but the underlying name will never change.
This is because Google Scholar was built by, and for, cis men with unchanging Western-style names. The "almost anyone" who you can search for excludes trans people, among a lot of other people it represents poorly. And because Scholar will not change, it should perish.
