I agree with @Flickersy . Of course this would be absurd. This is exactly why the newspapers are making up these stories, to make "the left" look deranged and absurd.
This is just an example, but I have seen so many headlines talking about "furries" in connection to this issue. Any journalist who had bothered to do even a 5 second google would know that furries do not identify as literal animals. Furries are exclusively into anthropomorphised animals, typically cartoon-style. These journalists are not lazy, they're getting a rise out of us on purpose, by feeding us falsehoods.
OP, you asked me why we should take trans kids seriously, but not cat kids. I actually think that both the left and the right have massively failed trans kids by taking them too seriously. I do not think that they should be operated on. Perhaps if we had all been less quick to jump on news reports and getting outraged over boys wearing dresses even though they're not literally girls, there wouldn't be so many operations on kids today.
