I was really trying to come from a helpful place. I did say detransitioning was very rare (twice to try to emphasise it). I thought it was important to talk about because it's one of the first things I thought about and had to research when my son transitioned to alleviate my own concerns.
I don't completely remember where I got that SA idea from (I know I didn't make it up). But, I can't verify it now, so I am happy to be corrected on that.
