Your 'points' are gibberish
~Just after his first 6 formative years, this boy raised by two lesbians suddenly wants to femalize himself by genital mutilation. "Gender identity disorder" could also be called "my gender doesn't matter disorder."
Anectdote- and as I have shown- children with gender disorder occur in families with heterosexuals also- gibberish.
I will take the only point you answered. The rest you just said "are gibberish", which shows your fear of them and inability to counter with lucid points.
As to the one point you did answer, a child can grow to hate his gender in any type of home. Yet in a homosexually-parented home, that propensity would rise astronomically. Imagine as a child and the first 6 years of life, your formative years, seeing in your primary environment ONLY one gender represented "as adults"...in a very young child's mind "as the entire world"..so your view of the entire world is just that one gender as mattering or significant. And you see that as "society-stamped normal" (marriage).
It is the incentivized institutionalized-maladjusted environment quintessential, whereas in some dysfunctional hetero marriages that might occur randomly as its imperfections in individual cases present themselves. It isn't insitutionalized, it's "random-unfortunateness"..and seen and presented as not acceptable for those children. Attempts would be made to change that environment for their welfare.
So if that child of "gay parents" happens to be of the same gender, it's probably pretty cool, if even they grow up stunted as to the opposite gender and how to relate to them. But if that child happens to be of the opposite gender, we can predict that would be murderous to their self esteem and view of their own importance in the world in general.
Like I said, I lived around gays aplenty when near the Bay Area. Without exception, every single lesbian I ever met was down on men, usually became that way because of a negative experience with men (the lipstick ones for sure...while they still sought out all the trappings of "male" in their butch partner, ironically...). Their negative comments and affects towards men/males seeped out of their pores 24/7. Imagine being a boy raised in that home. Well...this perfectly normal and happy looking lesbian couple (follow the link for pictures), turned out a boy who felt so insignificant, so "not-mattering"...that he tried to mutilate his junk at age 7...what do you know...just at the end of his formative years when his reasoning started to take over..
The lesbian parents of an 11-year-old boy who is undergoing the process of becoming a girl last night defended the decision, claiming it was better for a child to have a sex change when young....Thomas Lobel, who now calls himself Tammy, is undergoing controversial hormone blocking treatment in Berkeley, California to stop him going through puberty as a boy...
At age seven, after threatening genital mutilation on himself, psychiatrists diagnosed Thomas with gender identity disorder. By the age of eight, he began transitioning. ...
The hormone-suppressant, implanted in his upper left arm, will postpone the 11-year-old developing broad shoulders, deep voice and facial hair.

Just after his first 6 formative years, this boy raised by two lesbians suddenly wants to femalize himself by genital mutilation. "Gender identity disorder" could also be called "my gender doesn't matter disorder". And like I said, the APA isn't interested in doing a survey of children on a couch of their deep reasons for hating or rejecting their own gender. The results might interfere with prefabricated conclusions a la the neo-gay CQR method of rejecting facts in favor of audited group-think at the American Psychological Association (see OP links for details).
We cannot have pesky facts and common sense getting in the way of LGBT-approved "pre-conclusions" at the APA!
