that is a non-sequitur. the conclusion doesnt follow from the premises.
The problem is that many women (who are not trans) have a Y chromosome. They are either XXY (Klinefelter), or XY (Swyer), XY mosaicism, or any of the other intersex conditions.
Are those people not women? They may have fallopian tubes, a vagina, and a uterus, but also a Y chromosome.
why? Do feminists already "exclude" cis-men?
"Men can't be feminists" is a hotly debated talking point in the feminist community.
