How would a transgender 'girl' know that 'girls don't have a penis'?

Provide a source that "most 3-4 year old children" have been exposed to nudity of the opposite sex at that age.

I sure as hell don't know of any parents who take their child swimming naked in a public place with other naked adults - I think you're the exception.

 

I think that sex with your sister was more commonplace back then actually.

That's a bit odd - I sure can't imagine doing that with my kid - not gonna risk the possibility of being slapped with molestation charges - that (*)(*)(*)(*) happens - parents have been charged as molesters just for being naked around their kids in their own home, or taking scrapbook pictures of their naked kids bathing

Not go swimming if she can't get someone to watch her kid?

What age did you become aware of that at? 3 years? 1 year old? 3 months old? While you were still a fetus? An embryo?

 

Facial features among genders are totally different.

 

Right, meaning a transgendered "woman" still has male facial features, hands, bone structure, etc - not to mention chromosomes

 

Did you ever ask your dad that question? Or were you absolutely positive that he had one when you were that age?

Clearly you knew that there were obvious differences between boys and girls, men and women which is why you asked your mother that question and not also your father.

 

Didn't you start this thread? Why are you putting the burden of proof on him? I can't say I specifically remember how old I was when I started to become aware, but certainly some things like boobs are obvious... as for how awareness can happen, it's really not that hard.

Anybody that's had a brother or sister or cousins of similar age has probably seen a diaper be changed at some point when they were young. I remember my cousins would frequently come out of the bathroom naked, telling their mother how they went to the bathroom with pride... naked and in plane sight of anybody else who was in the room. Sometimes they'd run naked around the house while mom or grandma chased them down with cloths, telling them to get over there. Young brothers and sisters are sometimes bathed together. Kids, unaware of the taboo (or perhaps BECAUSE of the taboo) will sometimes just show things to each other, sometimes intentionally, sometimes unintentionally. Maybe my big old mormon family was different than yours, but it seems odd to me that you would not see how this kid of exposure is common or likely... unless maybe if you grew up as an only child and were not around your cousins very much. Still, as you pointed out earlier, you were aware enough to ask your mother if she had a penis, which means even you had to have been exposed to the concept enough to ask.
