No matter how many testimonies, how much anecdotal evidence there is, how many people talk about their own childhood experiences and fantasies...you're still clinging to this???

You are kidding yourself if you don't think that there are plentyyyyy of pubescent kids who fantasize about and would love a sexual experience with an attractive adult of their preferred gender.

The fact that Ethan and his ideological brethren cling to such notions shouldn't be surprising, Entelechy. The strongly emotional need to believe that children are more or less asexual is a very important component of the cultural paradigm of the Innocent Child that contemporary Western society worships to a degree of intensity that rivals Christian fealty to what Jesus Christ represents to them. Emotion is not logical, and it doesn't make any sense. This is why belief in the irrational lies upon emotion, and such beliefs can manifest in secular form as much as in sectarian aspects. In other words, the most die hard atheist can be prone to certain irrational beliefs based upon clinging to emotion; their irrational beliefs simply will not take a sectarian form.

Ethan won't be convinced by any degree of research or overt testimonials because the status quo institutions he supports are built on a gerontocentric empire that makes public acceptance and even quasi-worship of the myths connected to the paradigm of the Innocent Child essential. So basically, he won't be convinced because he doesn't want to be convinced. He isn't "open" to data that does not support the socio-cultural party line. It's really that simple.
