The rationale that many people follow is that if gender is socially constructed, it can be socially changed as well (through conversion therapy) to make your kid align with their assigned gender at birth, which doesn't work in reality.
Those people should probably read more. While a social construct does not have an absolute origin, that something is a social construct has never implied that it’s “fake.”
Especially at the level of the individual, where the gender “construct” becomes a monolith and internal and external perceptions belong to one person, it contains the entire definition for that individual at a point in time. So for the individual at a point in time, the construct is not only real, it’s literally all there is.
Changing the social definition of the concepts of gender, and how people view themselves are completely distinct.
I can paint new directions on the face of a compass , but it's still going to point where it was going to point regardless.
North is a social construct, but no amount of conversation therapy is ever going to move the north star.
