... are men who have chosen to identify as trans women, that is people who to a greater or lesser degree adopt the cultural stereotypes generally associated with biological women.
It may be that many of these stereotypes are not in fact displayed by biological women (such as make-up, long hair and dresses).
Some transgender women take female hormones
Some transgender women also seek cosmetic surgery which includes feminising of faces, breast surgery and removal of the penis, although, contrary to common thought, only a very small minority of transgender women undergo this procedure.
Irrespective of the number of measures taken by an individual, at no point does a transgender woman cease being a biological male.
It is right and proper that transgender women are treated as equal human beings with equal rights. But as they remain biologically male that does not include access to women's only spaces such as refuges, changing rooms, prisons or women's sports.
None of the above should be in the least bit controversial.
