Trans women are trans women. They’re not women. The trans label is there to differentiate the two terms, because biological women are different than trans women are

Uh… ‘trans’ and ‘biological’ are the labels… Trans women and biological women are women. The distinction you made is rooted in the idea that women must have female reproductive organs, which is just a description of biological women. That is why we use the label ‘biological,’ to distinguish biological women from women as a whole.
