And his wife is OK with this and the wider family have no issues with their kids being around this
Have the couple in question (Stephonknee's "adoptive" parents, IE co-enablers, co-fetishists and co-lunatics) got other children? Like, young children?
If so, then in any other circumstances those children would be recognised as at risk of grooming and possibly be taken into care.
Here's the thing: if you declare yourself trans, any amount of inappropriate, sexualised behaviour around children, which would normally be recognised as dangerous to children, will be excused and explained as an expression of identity. This is going to do serious damage to children, particularly in the case of their fathers transitioning and then hanging out with other men who call themselves women and have a conception of women as sexualised Barbie-dolls.
A bit like when India Willoughby explained h* threatening male behaviour in the Big Brother house, when India used h* big male voice and big male presence, to intimidate the women in the house, as being the equivalent of teenage behaviour because of only having been a "woman" for a short time, growing into that role. And therefore being a natural development stage which others simply need to manage, the way we manage teenage tantrums.
It's a fucking brilliant get out clause to excuse any type of male bad behaviour around women and children, whether that be dominant bullying tantruming such as India exhibited, or creepy sexualised behaviour that so many men who call themselves women or transwomen, engage in.
