Only the part before she started "pretending". Lets say she pretended for 10 years. Does 10 years of Black lived experience make her as Black as a 10 year old Black child? And trans-women? Do they not count as women if they transition too late? Picking some arbitrary age before which you have to be seen as X by society to count as really X seems just that - arbitrary, and very inconsistently applied.
