I have had a quick look at this, and will have to return to it when I am feeling a bit more robust. At first glance, Issendai appears to be saying that it is always parents who don’t listen and always their children who are trying to be heard because they don’t want to be estranged from their parents. Gender critical parents of adult transgender children have a different perspective, typically that their children have been indoctrinated into believing that disagreement means that their parents hate them, are transphobic and bigoted. Frequently there are further complexities.
In my case, we are not totally estranged, my wife is not in exactly the same position as I am, and my son is not in exactly the same position as his partner, and there other family members involved in the tangled web of strained relationships. One person, and one person only, is unwilling or unable to talk and listen, and that is not a parent.
I am not in a position to talk about the ‘missing reasons’ somewhere as public as this, even if it was of any interest to anyone outside our particular family situation. But I could quote, fairly accurately, what was said to me, in which ‘transphobic’ and ‘bigoted’ featured entirely predictably.
