Is this the "Bayswater abuse" you're thinking of?

It's quite the hit job. On the face of it, it's about parents taking away their child's possessions and forbidding them from interacting with friends. Peel it back a layer and it's similar to any safeguarding approach that a parent may take if their child is getting pulled irreversibly towards harm. Not all parents will make good decisions but the fear of watching their child potentially end up physically harmed (body parts amputated, brain development impacted, endocrine system damaged beyond repair etc) can easily lead to a level of desperation that thankfully most parents won't ever have to face.
Take breast binders for example. I can understand why a parent would destroy these, given the known and permanent damage they can do to the spine and breast tissue. I don't know if it's the approach that I would take but everyone parents differently.
To make things more difficult for parents, "the system" doesn't even recognise the safeguarding issues at play. If vulnrtable child is being coerced into friendships that lead to county lines and isolation from the family into a gang, adults in schools and supporting services know it's vitally important to work with families. Likewise under Prevent when a child is being pulled towards acts of religious extremism.
But where a child is being pulled into a belief system that tells them that a) they have a gender identity that is separate from their sex and b) they may need to alter their body to match this if it's different from their sex no such safeguards exist. Instead, parents are seen as a risk to their child. Loving, supporting parents who want to desperately help their child.
I'm amazed you can read the OP's request for help and equate it with racism or homophobia with the word "queer" (which is a word that means all sorts of things these days and many gay people find offensive).
Being black (or of any other ethnicity) is a fact. Sadly, some people are racist and don't want their children in mixed-race relationships. That has nothing to do with this post.
Some people are gay. Unless they are encouraged to confuse their emerging feelings of same-sex attraction with being trapped in the wrong body (which is inherently homophobic because it suggests that a gay person might actually be a straight person trapped in the wrong body), they are not at risk of removing body parts etc.
It's not "managing" a child to recognise that they need help and support during a difficult time in their life. That this may be exacerbated and influenced by others (see above re county lines and religious extremism). To borrow your quote: "Jesus, this is basic parenting".
