"Since Searyl is a baby, they can't yet identify their true gender. "
Supposing this baby is a girl, this should read: "... she can't yet identify her true gender."
Using the plural they and their confuses the reader. Never mind the fact that it's a grammatical nightmare. But the whole thing is absurd, really. What percentage of the population does this represent, I wonder? Not counting the children that have been inappropriately indoctrinated, of course. -.-
Well the correct gender neutral term would be "it", but that's not going to suit the PR narrative.
