Not a TAAT as such but just read on another thread that step parenting is easier across genders so that men find it easier to step parent girls and women easier to step parent boys. I think it's possibly one of the most stereotypical based assumptions I've ever read on mumsnet and struggle to believe anyone would believe such nonsense.
Is this a thing? Do people seriously believe that one gender is easier to step parent than another? I'm not sure which of the 72 genders they meant but referred to boy and girl so assume they meant sex.
