I'd still like to read the context not the paraphrasing of someone on very much the other side, from a movement that has made great capital out of asserting any opposition is hate and is therefore highly motivated to the worst possible reading of others' words.
I have not forgotten how the lady who quoted the very well known passage about "the big lie" to show how gender ideology was using the same methods as Naziism was gleefully reported by trans activisits as "we told you TERFS are Nazis, she even quoted Hitler!!!"
The "little bit of poo" analogy is widely used to explain that even if most of something is good, a small amount of very bad that cannot be removed from the good may be bad enough that the whole thing can't be done.
From the quote I read, she might indeed have meant "all trans kids are like shit", but she might also have meant "most trans identifying kids are fine but some are badly behaved or otherwise impacting the rest if the school" or "this ideology is harmful so even if it's only a few kids who actually identify as trans, endorsing the belief that mental gender exists and is more significant than sex has a bad impact on the whole community"
All I've been able to find so far is Trans Activits and allies gleefully performing aghastness.
