If you watch the oral evidence to the Trans Equality Enquiry there is one session specifically dealing with hate crime (with Helen Belcher and a legal academic specialising in hate crime). What the TRAs wanted, and still haven't achieved is for "incitement to transphobic hatred" to be made a criminal offence in and of itself in the same way it is now with racism and homophobia. Which would probably include any negative speech about transgender ideology/misgendering/deadnaming/GC women's protests and meetings.
It's worth remembering that lesbian gender critical women can report the frequent threatening homophobia towards them under this "incitement to hatred on the grounds of sexual orientation" law, if they are so inclined.
From Sussex police website:
"It is a crime to intentionally stir up hatred based^ on sexual orientation by^ using threatening words, behaviour or displaying written material (section 29B of the Public Order Act 1986)
.
The relevant threatening conduct could be in words, pictures, videos, and even music. Illegal hate content can include messages calling for violence against LGB people, web pages with images or descriptions of violence against LGB people, or chat forums where people ask other people to commit hate crimes.
There is no specific crime of incitement to transphobic hatred but there are general laws that prevent someone encouraging others to commit crimes, including sections 44 and 45 of the Serious Crime Act 2007. Repeated use of offensive or insulting language can also be treated using the offence of harassment under the Protection from Harassment Act 1997. If you become aware of hate material, you can tell the police about it or an LGBT charity.
