Of course justice involves political agendas. How do you think poll taxes and literacy tests were eliminated? We don't even have to go that far back -- the legal recognition (& protection) of same-sex marriages is something even zoomers have a memory of.
People opposed to social justice aren't apolitical or morally neutral. Banning books, getting educators fired, and forcibly de-transitioning children are all charged political agendas in and of themselves. They all fall under the umbrella of "anti-SJW/woke" brigadism.
It is possible to largely be for social justice while disagreeing with some of the beliefs of the modern Social Justice movement. I know scientists that fall on both sides of the debate when it comes to issues like MIT cancelling Dorian Abbot's lecture or Thomas Jefferson HS changing their admissions policies. I don't know any scientists that have any of the "anti-SJW" beliefs that you've listed.
I also know some 18 year old robotics kids that are just truly indifferent about this stuff. I suspect some of them will grow out of it, but even for the ones that don't, I don't think that says much about their qualifications for Yale. Climate change is a massively important issue yet we don't ask random humanities students what they've done to improve climate research.
Banning books and firing teachers is one thing, and I agree we should protect free speech.
However, I'm not sure I'm okay with the idea that feeding complex hormones to children who are not old enough to vote, drive, or get tattoos and/or piercings, or as you so put it is wise, and if this is what you mean by "forcibly de-transitioning children", then I'm actually okay with it.
Hormone therapy, like tattoos and/or piercings has a very permanent effect of the body. I believe such long term changes should only be allowed if the person is old enough to take the decision as an "informed adult".
Put more bluntly, if all of a sudden some new condition is discovered called "un-inked skin skin dysphoria", where not having a tattoo is believed to cause deep psychological trauma, I'd still make my kid wait to be a legal adult before they get a tattoo.
