I am probably your mom's age or even older. If your mom is heterosexual, or a bisexual woman, who has had her fair share of sexual relationships over the course of her life, or she knows and speaks frankly with female friends and relatives about their sexual experiences and relationships, I am pretty positive that she has met or knows of at least one het relationship in which the male partner is an AGP cross-dresser who in today's climate would be calling himself "trans" and saying he's a real woman and always has been.

This is not new behavior on the part of males. Both het and homosexual males who want to be women and who call themselves women have been around since at least the 1950s; earlier if we look at the historical record. What's changed now is how public, emboldened and powerful these men have become. The other thing that has changed is how many other people of both sexes are jumping on the trans bandwagon, and developing "gender dysphoria" - or at least labelling the unhappiness and mental distress they experience as "gender dysphoria."
