Yeah, well, while some of their ideas could have been expressed better, I do agree with some of what they're saying, including being transgendered as a psychological condition (which is axiomatic, surely). I also agree with the concept of "educating people that they don't have to do this [transition]". I identify with this latter point. I've been confused about my gender since childhood and have been on several courses of HRT, yet I feel no closer to understanding where my head's at regarding my gender, let alone transitioning. Many transgendered people, myself included, do not yet know, may never know, which transgender narrative(s) applies to them. Yes, maybe, probably, I'm gender fluid. But honestly, I really don't know.
What I do know, however, is that someone suggesting that I'm "not bright enough" to understand the nature of my gender is rude, intolerant and totally counter to what transgendered people everywhere (I'm assuming) hope to achieve. That is, widespread understanding and tolerance about transgender issues at the level of the individual and the wider community. To shut down or lambast some transgender experiences over others is to suggest that we know all there is to know about being transgendered -- we do not.
In my opinion, the sharing of ideas among transgendered people should not be met with intolerance. I for one am glad that people speak out about their trans experiences, no matter how their personal experiences are unfolding. It's really helpful. If you are party to censoring, condemning or shaming people whose transgendered experiences you don't agree with, then I think you're party to shutting down potentially important insights that someone other than yourself might find invaluable. Who knows, perhaps you'll also learn something.
