I agree that it is a useful narrative for transactivists to push. It is a shame people like the Liberal Democrats, the Greens, Labour (and even many Conservatives) fall for it, stop thinking for themselves and lean towards a trans propaganda stance for fear of seeming right wing. Maimonides said wisely that we should recognise the truth wherever it comes from. Not that opposing this cult just comes from Trump and American Evangelical Christians.
People who have nothing to do them have been aware of and troubled by the transgender queer theory trend before they were. And it is actually the doctor here who is him/herself the tool or mouthpiece of an authoritarian agenda driving an ideology.
Doctors like this one in Brighton, pushing through treatments on children without sound psychological prior exploration, who may well effectively be the homophobic ones.
Many GC women who are not right wing have funded recent U.K. court cases and JK Rowling is a special example As for those cases funded by Christians they are fewer, but when they are, that does not make any case more or less legitimate.
This ‘GC is fascist’ narrative is so far off the truth, and so offensive, somehow implying (if we think of the case in the OP) that a parent not wanting their child to get caught up in the hands of a doctor like this, is someone under the cosh of fascists.
edited to add Conservatives.
