People are being dishonest when they say that transage has no basis in science.
For a long time we had doctors and lawyers and other professionals talking about certain individuals as having mental or physical ages that were different from the length of time since they were born.
Major cases were beijg debated where someone's psychological age (as opposed to chronological age) was being regarded as relevant in making medical and legal decisions.
Psychologists and regular-ass people talking for a long time about emotional and mental maturity ("manchildren" and "kidults" who were "eternal boys" suffering from "peter pan syndrome" with "stunted cognitive/emotional maturity", unable to "adult" properly)
Even now some men talk about their ideal girlfriend/wife taking on the role of being their second mother or personal maids/therapists in addition to being their lovers, aka having a significant other that is somewhat like an adoptive single mom you can fool around with taking care of you as an adult.
In each case, the actual age of the individual was treated as less important than how it was in contrast to the age at which their behavior or degree of capability would be considered appropriate.
Everyone was totally accepting of this as being a legitimate claim to make about people and no question was asked, nor opposition voiced, until some people started suggesting this was a valid basis for an age identity that was different from chronological age.
What's funny is that before transage became a thing, those accused of being mentally younger than they were would deny this assertion, but today they accept this as being not only true of them, but asking about how society could accommodate them due to this.
So now those who would say to us that we were "children in the bodies of men" have made a polar switch in their analysis of us. Now we are the ones making that claim about ourselves, owning what was once an insult used to shame us for not conforming to the expectations they'd had about our chronological ages.
In response, the normies have completely backtracked on their past claims, to the point that they pretend not to have ever made such statements, and they now deny the potential legitimacy of such claims.
The best course of action to take is to dredge up past examples of the language used to describe people like ourselves, to remind them that transage concepts have been in popular parlance for about as long as modern psychology had been a thing, and very possibly for longer than that.
It was totally fine as an insult, description, or medical/legal diagnosis, up until people like us started suggesting that it was actually a valid basis for identity.
Weakness and victimhood are strengths in the overly compassionate world of today, they are weapons that can be used to move society and change its culture.
