While I deeply disagree and detest the use of the term "groomer", the people who are doing so, are doing so in reaction to this dogma. Mind you, this is not about sexual minorities, but about infringing on child-parent relationships. As far as I best know (I can be wrong), the dogma is largely unsubstantiated, and it is not majority accepted in most places around the world (look at the UK for instance). Mind you, this is not about trans or gay acceptance, but the rejection of the biological sex binary, the conflation of sex and gender, and the subversion of parent-teacher relationships in favour of this dogma.
Furthermore, I don't think "groomer" is the modern newspeak. If anything, the dogma that the terrible term "groomer" was meant to counter has the support of countless of mainstream institutions, academic, political, medical, news establishments, etc. Unless you live in a pure conservative bubble of any sorts, the dogma is word, the dogma is the newspeak; for starters, painting actual bigots and people who have compassion for these minorities (but refuse to toe the line behind this dogma) with the same brush by calling them "would-be killers". As such, there is a middle ground to be found, a minority of extremists such as yourself just get in the way.
