"...over 80% of nonbinary people believe that identifying as nonbinary would hurt their job search. Similarly, 51% believe their gender identity has affected their workplace experience 'very or somewhat negatively.'"

What you believe and what you can prove are two different things. I'm not saying there's not som bias there, but I doubt if it's about identity, it's more about hiring people who don't immediately sound like they're going to be an HR problem day one. Non-binary people are probably more likely (I have no sourcer but anecdotal) to run to HR because someone didn't respect their pronouns. Who wants to deal with that shit? They are the Karens of the LGBT community and you know they're going to the manager.

Also sounds like MSM is getting bored with the trans community and picked a new victim of the week to talk about.
