I think Women's place are doing that at the moment - in the face of attempts to discredit them - and i think if they can hold that line there might be progress. I'm not so sure that all MPs are behind having open respectful debate though - they are all so far avoiding this like the plague & are clearly cowed by the threats to their positions, should the transphobic slurs fly.
I don't see how any respectful open discussions can be had with that looming large. Women's place are certainly trying to get this in the open and yet every meeting is having to be kept secret because of the threats to businesses & venues.
How can anyone move on this when even debate is being actively shut down like this? No political party have had or intend having anything like an open debate & make policy decisions on this without consultation. People's jobs threatened. Doxxing. It's all madness & if a debate could actually go ahead that would be great - in these circumstances I've no idea how that happens with these types of tactics employed before talking even takes place.
