You can be fair to people with trans issues without denying natural female gender and denying them safe women only spaces.
This.
It is very apparent that for some men, trans issues are being used as an excuse to let loose their gynephobia. When you have a man seriously trying to say that the entire class of female sex should not be entitled to privacy, dignity, safety, freedom from harassment, the right to group by their sex, their right not to be forced to undress in front of a male, regardless of their own feelings, needs, faith and beliefs..... because the possible need of a male person outweighs all of it?
It's no longer excusable.
It's also ridiculous that it exposes while talking about 'no such thing as sex' is their given reason for this, they are demonstrating entirely sex based thinking, in which one sex class is subordinate to, lesser than and for the use of the other sex. The language borrowed from trans people is just being used to further their personal gynephobic agenda.
