If you look back through her archives, there was a time when Richard Littlejohn and other Daily Mail journalists were regularly talking about her. And she would, without fail, write at least one lengthy blog post about every negative article, sometimes threatening legal action. She once even got a Guardian article out of it.
As an aside, that shows how monumentally thick Jack is - kicking up a fuss over a Mail article ensures more people will go and read it, and in turn the Mail will publish more about her, because it works.
Anyway, that was back when Jack was having her moment of glory. Whenever she talks about trolls, most squiggles still picture Littlejohn, Katie Hopkins, and an angry far-right mob shouting, "But if she's a lesbian how did she get pregnant?!" Plus, if Jack gets any criticism along these lines, she tends to share it (like the totally not made up Peter this time last year).
It serves her purposes very well to paint her detractors as far-right bigots, rather than people who keep tapping the numbers into their wooden calculators and finding that nothing adds up.
