If I can responsibly say to "object" to anything it's people being rushed on a path to gender transition, given the heavy costs that this involves in practice and the fact that some steps are irreversible (including male hormones for those AFAB - though admittedly this might also make it more justifiably salient for someone AMAB to seek to delay their puberty).

This applies to kids the most (they of course aren't at risk for surgery, but the usual notion of a fixed "gender identity" is also least sensibly applied to them), but people in young adulthood should also be a bit concerned. Research seems to show that, by and large, those who transition in middle-age are the happiest post-transition. I'm not sure how that squares with your feeling that someone with my views might just find "trans people unacceptable in general"; my concerns are derived from real-world practicality.
