Is it a trial in Leeds? First I've heard of it.
It's been running for several years, there have been numerous news reports, not just in Leeds but nationally (including the BBC and Guardian).
If you campaigned about these issues rather than transwomen, I'd happily engage with the Feminism section.
We have. There have been numerous threads, letter writing campaigns (I've been in touch with my MP about it), fund raising for Nordic Model Now (nordicmodelnow.org) and grass roots organisations in Leeds.
In response to which, Leeds City Council commissioned an "independent" (my arse) study by a pro-prostitution academic which carefully neglected to ask local residents about the impact on them and came out with a "nothing to see here, move along now" conclusion.
Anyway, now you know about it, I'm glad you'll be getting involved - the link to Nordic Model Now should give you some pointers.
