There is no such thing as God
I sometimes wonder how people with this logic tend to overlook all the straight parents having LGBTQIA+ children
Straight is normal though and is the usual, default human experience, so of course the majority of "trans kids" are from straight parents. You aren't expecting gay parents or post-surgery trans to be having kids, do you?
Anyways, like I said I just wondered why trans parents have "trans kids" often, at least more often per capita than straight parents.
