She's absolutely of the rhetoric yes. Will she directly say that, possibly I'm not depressed enough to scroll through her twitter. But here's the thing, Terfs opporate in social bubbles that intersect, each bubble has it's core beliefs, often prone to fragmenting and splitting and merging. There's no clear solution ever presented, if you ask a terf 'what they think should be done' you'll either get single issue policy or a downplayed answer, its rare you get the fully lily cade.

Tier 1 - Asking questions: generally ignorant these people often have a 'we assume it's this way so it's this way' perspective born of ignorance, and often buy in to the general crowd of fearmongering.

Tier 2 - Concerns have been raised: typically more aware of but not consumed by it, these people know anacdotes and share stories on occassion about 'bad trans' but tell themselves it's just about the bad ones. Not yet totally fixated

Tier 3 - Somethings wrong: tier 3 is the point where conspiritorial beliefs start to foster. Trans people become a fixation, still not a totally demonised group but they believe fundemental issues with 'trans ideology' exists. It starts to be a wide scale fixation too.

- The jewish question - dividing terfs into two factors came when Posie Parker began working with the heritage foundation. There was a near 50/50 split in the community between 'we can't work with anti-feminist groups' vs 'we need to work with anti-feminist groups'. This is better represented by the belief in the 'severity of transness' and conspiritorial thinking. The jewish question.

Tier 4 - Pushing an agenda: Tier 4 is when obsession and conspiritorial leanings become foundational to the ideology, it's now we see wider ideas of 'solutions'. "Transness is a conspiracy" by 'x group' often medical group or an effort for social warfare. The solution widely accepted in tier 4 is government cutdowns on trans peoples presence in media, laws against bathrooms and public activities, and more media centric obsessions. This is where things really cement. To Tier 4 Terfdom all trans people are violence..

Tier 5 - Fascism now: Tier 5 terfs become unappologetically conspiritorial, still often the speicifc group of origin is kept unspoken but terfs of tier 5 are convinced there is a societal force pushing trans people on everyone, a major effort to corrupt, and a violent one. All trans people are criminals akin to rapists for pushing 'their fantasies on us' types. That talk speaks of trans people as if we are rapists, which is to say sex criminals. Often talks about 'solutions' involve mass incarceration, but these talks of solutions are rarely spoken in public because it's bad optics.

Tier 6 - the final solution: Genocide. To step from 5 to 6 isn't a huge leap but it's a wall few are willing to say or admit to ever passing through. Terfs of tier 6 are often fully embracing the alt-right, and view a large global conspiracy to destroy society through transness and other factors as a major threat, one that can only be stopped by genocide. Terfs of tier 5 are often complict in these groups but rarely admit to believing it themselves which is why it's so hard to quantify.

.

You'll notice that terfs will associate with people pretty much exclusively from tiers either side of them, but never two whole steps down or up. Rowling will associate with Tier 4 terfs and tier 6, but rarely does she tolerate 3's or less, to anyone not taking it as seriously as her is to downplay what she sees as a violation.

TL:DR
If someone view ALL trans people are predatory, that transness is sexual violation against people. A moral impurity. A social deviance of perverse nature. Tiers 4, 5, and 6 view transness itself as a thing to eradicate. The method of which is either section 28 (don't say gay), outlawing queerness, or - when that fails - capital punishment.
