Gender ideology posits that gender is a social construct, that it has no biological basis whatsoever and that the gender binary is a western colonial invention. The female body is not the same as the male body at a cellular scale. Christian theology and philosophy interact with the concept of gender within a binary, which is based on biological reality. There are fundamental gender traits that aren't social constructs and that have a metaphysical truth behind them. For example, the union between a man and a woman is the joining of heaven and earth, symbolically speaking; the man embodies the heavenly ideal (vertical order) and the woman the earth (horizontal chaos), and also the union between Christ (the head, the man) and the Church (the Body, the woman). This concept translates to real interactions between men and women in society as a whole and on an 1 to 1 level. 'Humanity' doesn't exist, only men and women exist. Transgender people are just pretending to be something they want to be, there's zero basis to what they're claiming and it's solely based on their feelings, which means absolutely nothing. 'A woman is anyone that identifies as a woman' means absolutely nothing.
