I think the reason Jack responded to that teacher's tweet (which I agree was vile), even though in her own words it had already had loads of criticism, was because now it will almost invite abusive tweets to Jack from the gender critical side of twitter.
And then, she can use that to stack up her unfounded claims that the 'smear campaign' is from a GC or Tory audience.
Even though most of the most recent twitter scrutiny (not abuse, scrutiny) has been about her dangerous food shops and Patreon grifting.
If Hunger Hurts 4 materialises I reckon it will be about her non-binariness and the alleged hate campaign against her because of that.
And for someone who likes to throw around the libel threats she needs to be very careful she doesn't name anyone who has criticised her and claim it's because they're GC.
Just my thoughts. Might be wrong of course.
