Thanks as ever to MNHQ for allowing this debate. I appreciate what a lot of work it must be 
Sex is a protected characteristic.
We need to be able to name sex. We need to be able to say whether a person is male or female. If we can't do that, we can't do feminism. Might as well close the board.
'TIM' is not synonymous with 'trans woman'. It's an umbrella term for all the male people who have a trans identity, or who say they do: transwomen, transfeminine, genderqueer, non-binary etc. plus males with a crossdressing fetish, those who are IDing to prey on women and girls and those who are just taking the piss.
We need a word for the entire group of male people who we are being pressured to accept in female spaces (in the widest sense).
This is nothing to do with how any particular individual in this group might identify. It's to do with the fact they are male. The debate is not 'about what it is acceptable to say, or not to say, about trans people, and changing opinions about gender and sex'.
The debate is about women's rights and how we preserve them.
Maybe we should just keep TIM, TIF, TERF and cis? And everyone can lump it all round?
Yes I agree with this. None of these words should be used as a personal attack but beyond that they should be allowed.
We’ll be introducing a three strikes system whereby users deleted more than three times in any rolling six week period will have their membership automatically suspended and we’ll then take a view as to whether they will have membership reinstated.
If you can automate this you can automate notifications so that posters know they've had something deleted.
This will be gamed horribly though and I think it's a big mistake.
