"Advocates" is probably a better descriptor than mine tbh. Anyways, here's how I counted.

1. "cutting a boy's penis off is an appropriate treatment for liking dolls" - Not a position held by trans people or allies. We support the rights of transgender and cisgender people to be as gender-non-conforming as they like.

Note re: "transed her son because her husband wasn't happen with his 'girly' interests" - Having seen the talk she gave that you are referring to, she made no claim of the sort. Also, 'transed' is not a word that describes a coherent concept that exists.

2. "why does he then need further intervention to be that girl" - Nobody needs any interventions to be a girl. "Girl" is just a label.

3. "a child who wants to be a girl totally needs to lose his dick and the parents are Nazi's if they question it" - Advocates do not believe this. Trans adults can have SRS if they want it but it's not "required" for anything and it is not offered for children.

4. "Where is the research showing that children come up with 'gender dysphoria' without adult prompting them" - Most transgender adults were once transgender children. It's quite common to see them say on twitter, tumblr, etc. that nobody told them about gender dysphoria when they were young, and that they had to create their own vocabulary for it when they tried to explain their feelings to their parents.

5. "these are the words they'd use and the interventions that they'd have asked for without 'therapists'" - This one is just confusing. Of course they wouldn't use the same words and independently develop the same medical treatments we have now.

Note re: Money and Reimer: Money was influential in early study of transgender people, but it's important to note that this does not make him an "advocate". Reimer was not transgender, and it always confuses me why anti-trans people think what happened to him supports them. He knew he was a boy, others ignored him, and he suffered greatly as a result, in many of the same ways that transgender people suffer when they aren't allowed to decide their gender for themselves.

Note re: "Why isn't the much more likely explanation - that these adults are pedophiles" - This is not a more likely explanation.

6. "Where, without an adult telling them that a sex change is a real thing is possible for them to have, do you have children asking to be surgically changed to look vaguely like (ie, cosmetic only) the other sex?" - Children generally do not ask for SRS. Apart from that, I'm not sure what your point is here?

7. "How many children, without weird homophobic parents, want their genitals surgically modified?" - This is pretty clearly a reference to the conspiracy theory that transition is a form of gay conversion therapy. Like many conspiracy theories, it's really stupid. Homophobes are generally transphobic as well. Many trans people were asked "why couldn't you just be gay" when they came out to their parents, showing that they see being transgender as worse than being gay (not that they would have approved if they were gay either). Also, only about a quarter of transgender people describe themselves as straight, compared to about 90% for the general population, so if it were a form of gay conversion therapy then it would probably be the most counterproductive form yet devised.

Note re: "explain why wanting to be a dinosaur doesn't warrant surgery but wanting to play with dolls does" - (This is a duplicate of #1, but to reiterate: ) Transgender and cisgender children have every right to play with whatever toys they want, regardless of what gender they are marketed to. It's the transphobes who say children should only play with toys that match their gender.

Note re: "why not just agree with me?" - Because you are wrong about many, many, many things. There's more than this that you're wrong about, but if I listed everything you were wrong about and gave long-form sourced arguments in rebuttal, it'd be a full-time job, and I'm not doing one of those unless I'm getting paid to do it.
