The organiser sadly tried to achieve something using unacceptable methods, which is why she has been called transphobic.
Had she merely asked for ,or arranged an event without transwomen she would have been legally entitled to. However in the course of doing this she used two images which are unacceptable to the transcommunity, one the person in lycra and the other an assault by a transwoman in the loo. (And yes I know they were both real). She used the worse stereotypes to justify her request, so indicating that this is how transwomen generally behave. It was transphobic to do so.
Can you point ut to those images please? The article in the OP tells us that the fact that these things had happened in the past had led her to point out that 'if you are not a woman you are not a lesbian', but I can see no images or references to images in the article - maybe you have read a different one, in which case it would be helpful to point to it, so that any information is available to all on the thread.
Sorry to be picky, but there are repeated cases of what appear to be blatant misinformation, twisting of people's words and false accusations on this thread (I apologise in advance if I am missing something) and it is important that we are talking about things that actually happened, not what you 'consider' to have happened.
Speaking of which - I note that there has been no link to the change in the EA either - was that another example of something that didn't happen? Telling us to Google it (the FOFO method so beloved of those who are talking about things they don't understand) is pointless if it didn't happen. If I asked people to google the Martians that have landed on Hampstead Heath (Analogy Alert - they haven't!!) then of course they wouldn't be able to find anything. That wouldn't mean that they were rubbish at basic research, or that I have a superior knowledge to them - it would mean that nothing is out there for them to find.

The above is rather turgid, but I would have thought that if the changes you report had happened they would be referenced here, but I can't find them. That may be my fault - I am still shaking off Covid - but as you are so well-versed in this particular aspect of the EA that you have quoted it many times on here, perhaps you could help me out (and the others who are unable to find it either)?
