That's the wrong way to look at it.
They have nothing in common with women at all. They have the wrong chromosomes, no female organs, internal or external (the simulacrums of vaginas and breasts they acquire are not female), their brains, physical development; everything is male.
Trans women don't have things in common with men, they are men.
They are also most welcome to claim to be women and take hormones that will give them the appearance of women. They're also most welcome to have equality with other genders and be protected from discrimination.
They're just not welcome to tell women what to do, share changing rooms, bathrooms, saunas or prisons with women.
I've been saying since the start - we built facilities for disabled people decades ago, now build some for the differently-gendered. Problem solved, and I'm dismissing their desire to be considered women to the extent that a beauty technician is called transphobic for not wanting to wax some bloke in a dress' dick.
Beautifully put!
