“At 2 years old, she started telling us she wasn’t a boy. At 4.5, she socially transitioned and at 7 she legally transitioned.”
That's not an answer. A 7 year old, "4.5" year old, and certainly a 2 year old doesn't know any of those things.
Unless they grew up fully exposed to sexual perversions.
What you say isn’t true, because HER PARENTS are that way. The behavior was without a doubt, modeled, and verbally taught to her. THAT is the evidence of the abuse.
