The safety of women is paramount - whatever points are raised to try and be inclusive to trans people.
As one of the "type 1s" the OP categorises, despite the fact I've gone through the entire medical process, keep myself to myself and live a happily boring mundane life I still recognise that I am biologically still male.
The trans movement, as it is now, IS a men's right movement based on appropriation of female identities/bodies and some kind of twisted identity validation.
And as much as I find the idea of having to share 3rd spaces with hairy a*sed AGPs in bad wigs and fishnets distasteful, MEN should not be using women's sex segretated spaces AT ALL. No matter how many "magical gender feelz" are hurt in the process, it's miniscule in comparison to the women who are being sexually assaulted, subjected to violence or are in genuine fear of their lives DAILY because of this nonsense.
Yes, transsexuals ARE going to get thrown under the bus as this carries on, but it should be us that's fighting ALONGSIDE you and speaking up to sort out this sad state of affairs. You, as women, shouldn't have to do it for us. It's not your job and not your fight.
Over the last few months, the TRAs are definitely rattled after being dragged into the daylight and exposed for what they are. Hopefully this year will be the year the tide actually turns.
