I agree, children are impressionable and they should not be railroaded into one way of thought. I'm not sure I understand what you mean by preserving innocence? Showing children healthy relationships seems like the best way to prepare them for adult life. Of course overly sexual relationships are not appropriate for children, but in this case the cartoon is just two adults kissing.

In terms of epigenomic expression I don't think that small reductions in testosterone are necessarily bad. Testosterone triggers a lot of bad biological processes, and the good ones it targets have to do with building muscle. With the future consisting of more and more automated 'hard-work' I don't think having large musculature will be an important human trait.
