You might have had a point, if trying to change the sex of infants was a "transgender issue".
Maybe it's just a sci-fi show exploring alien cultures, and showing what kind of diversity, for good or for bad, there is out there?
Mercer did use the phrase "transgender operation" to describe Topa's planned sex change. Which was kind of an eyeroll moment for me. It wasn't a phrase the Moclans would've used, and I don't think 25th century humans would use either, but I guess he picked up from 21st century pop culture.
It doesn't really describe the situation at all, except for in the loosest possible sense.
