Can't imagine why...
One problem, which I expressed in my first comment here, is that most people's experience of transgender politics is somewhat indirect. And where that's the case, you only really end up seeing the "worst" of it.
An essentially similar attitude permeates NJ's framing: there's no discussion about what changes in Amanda's life occur beyond changing her name, manner of dress, etc.; no acknowledgement of the potentially years or decades before she "suddenly wanted" to be addressed as a woman; and, perhaps more revealing still, there's always this tone of "demanding" access. There's never any room in this world view for being invited in. But there's far more acceptance of transgender people than all that, and very little acknowledgement of this.
It also goes without saying that this assumes by default that "man" and "woman" are inexorably tied to biology somehow. But that just bulldozes straight through the intellectual issue here, which is that gender and sex are different concepts, even if they are usually linked. But if you ignore that, or don't even engage with it, it's little wonder that everything else that's so dismissive of transgender people follows.
It's a horribly oversimplified view. Draw comfort from reducing the world to neat little boxes, if you wish, NJ, I won't stop you, but I do wish you'd engage more honestly with the complexity, with the variety, of the human experience, beyond your narrow perception of it. And, honestly, I'm still not sure why you seemed to determined to prove to me that you weren't yourself expressing anything bigoted. It was never the question.
