If gender is a social construct as the nut.....er...... author seems to be saying, how can she raise a baby as a girl? According to current liberal theory (which changes by the hour) she could not examine the baby's genitalia to determine the gender. Because as we all now know identifying the sex of a baby is well nigh impossible....liberals have told us as much.
The obvious solution is to wait for the child to reach an age where it can decide for itself whether he or she wants to be a he or a she. And then the indoctrination can start.
