It isn't criteria as such, and certainly has no bearing on decisions made, ( which are down to us as well as them )It was just him explaining that the difference simplifies matters for them. As for me i just still yearn to have peace of mind and a sense of being female. Don't imagine that taking hormones and having genital surgery makes you a woman just like that, it is either within you already ( type A ) or not quite as strong, as in type B.
Well I guess I'm cat A then, always have been
always will be. Whether they think that who knows, who cares I guess.
I hope you soon find peace of mind
