You know how I said John Scalzi was right about 99% of the time? Well, he did an essay recently that I really strongly feel is a must-read, because this is one of his best of that 99%.
I don't talk a ton about it, but I am the father of a trans child, and the issues he talks about in this essay are part of my everyday life as a parent. He really does a great job of hitting every important point, including the bit about having the self-awareness to understand that you're not going to get it right the first time and that you need to keep trying and not get defensive when someone points out that you got it wrong. Basically, this is really good Trans 101 stuff, and it deserves a read.
