Glad it all went so well last night.
A couple of points. There is a strict policy of no photos or video inside the venue in order to try and minimise the potential for women to be stalked and doxed by TRAs. It's very much their stock in trade. A lot of the women will have been victims of DVA and their privacy matters to women, or at least it should do, I realise there are a number of women, including one posting on this thread who would happily see other women thrown under any number of buses/killed by their violent exes for thinking the wrong things.
Secondly, the speeches are put on YouTube as is. The only time they might be edited is if they have accidentally filmed a member of the audience who is at risk of the actions I mentioned above.
Thirdly, on the subject of smears, if you have been the victim of sexual violence there is a women only specialist service in London and hopefully another is going to be set up in the North. Other than that, yes, legally you are able to withdraw consent for a medical procedure, on any basis, however, it will be marked on your notes and you will be regarded as 'difficult' from then on and treated accordingly so your boundaries may well mean that you're not taken as seriously, unhelpful when women are already not taken as seriously as men when it comes to medical things.
Lastly, lying about how a WPUK meeting went, when it can be amply demonstrated that that is what you're doing was probably not the best way to go. It makes you look like an utter fool.
