I guess it is acceptance, their parents grew up with madge, they all Vogued in their time
Its a generational change that happened to these kids straight parents without them (the parents) actually being aware of it at the time.
I notice this amongst my family/ friends and their kids my youngest nephew (5) recently told his younger sister (3) that men cant marry men and women cant marry women, when my brother in law explained to them that men can marry men, women can marry women and its normal for people to love each other no matter if they are all boys or all girls or girls and boys.
His dad was there and in such denial he just ran away and didn't want to talk about it.
I wonder how grandparents in the audience may have felt?
