Sure, I'll elaborate:
>> In some cases, sex or gender assignment does not align with future gender identity, and the assignment can be problematic.
For starters, while this is a fringe case (~0.3 - 0.6% is a lazy estimated range taken from Wikipedia) it takes up 2/5 of the introductory section.
Sex assignment not matching future gender identity "can be problematic". This is something I do not agree with; I'm of the opinion that gender and sex should be treated very much separately, and this posits that assigning a sex at birth is "potentially problematic" just because the person's gender might not match up later in life.
>> Reinforcing sex assignments through surgical and hormonal means may violate the individual's rights.
That's well and good, but this is only relevant for intersex people, and this seems to imply that it is also so for transgender children. Intersex occurs significantly less than transgenderism, at around 0.06% of the population.
This kind of thinking can and has resulted in the thinking that it is a child's right to determine their sex; see for instance the gender reassignment clinics in Canada that treat children as young as 4 years old. I find it very hard to envision a reasonable country where a child of 4 is given the choice to undergo intensive surgery which will also render them infertile.
It's already forbidden for Canadian schools to tell parents if their children are identifying as the opposite gender at school; I suspect the next step will be placing children out of their homes if their parents refuse to let them transition. A brave new world.
To add insult to injury, child gender reassignment surgery and the usage of puberty blockers are still highly experimental. A few things are known (like the decreased bone density) but many important questions remain unanswered, like the impact on brain development. It will be a long time before this is solved because there just aren't a lot of children undergoing sex reassignment surgeries, thank god.
>> Terminology
This section goes to great lengths to only use "Male" and "Female" in the context of "Assigned X at birth". In fact, the whole article contains not one mention of the names of the two sexes, except when narrating about people who do not "fit typical notions of male and female bodies", the one in "Terminology". Again, over half of this section is dominated by transgenderism-related text.
>> Assigned X at birth
To me this idea seems to imply that sex is something that is arbitrarily chosen by a Doctor at birth; the Doctor here being portrayed as the personification of "the Patriarchy". As if sex has nothing to with sexual organs and the means of procreation.
>> Sex reassignment: ... physically change a person's gender to match their gender identity after a putatively erroneous sex assignment at birth
"Physically change a person's gender". I don't agree that gender is a physical thing at all. I consider gender to be a set of social protocols that generally ease interactions between individuals, by providing a default set of roles a person of either gender can build their identity off, and while also easing day-to-day interactions between the sexes by defining common protocols.
"putatively erroneous sex assignment at birth" implies that gender dysphoria is more real than a person's sex, ignoring the fact that a person's sex does not change with "sexual reassignment surgery" as a person's chromosomes don't change and that person will never have the same sexual function as a person of the sex whose visual characteristics they imitate with surgery.
Neither this section or the rest of this article acknowledges that sex is in any way grounded in biological reality. There is a much better Wikipedia article on "Sex determination systems", but none of the information there is mentioned in the "Sex assignment" article. It's also not mentioned in the "See also" section.
>> Assignment in cases of infants with intersex traits, or cases of trauma
This belongs in the main article ("History of intersex surgery") but takes up twice as much as the introduction and Terminology section.
>> Challenges to requirements for sex assignment
"the perceived need to legally assign sex is increasingly being challenged": there goes the narrative again, "assigning sex is bad and you should feel bad".
