Great article. Thanks, Olivia for posting this.
This really made something click with me. That these colleges, as well as the governmental agencies that institute restrictive policies on how gender markers can be changed, are essentially asking us to "prove it".
Prove we're trans.
Prove we're really a woman or really a man.
Prove it by getting surgery, prove it with a letter from a doctor, prove it by getting our documents changed, etc.
