Should underaged characters be used in Forced Feminization fiction?

This appears to be a touchy subject for many within the community, with the general consensus divided into two main camps. The first assumes that underaged characters are acceptable because the scenario is purely fictional; no real person is being harmed. The opposing camp maintains that underaged characters should never be employed in transgendered fiction, as it might encourage the abuse of real life children. Needless to say, the issue isn't strictly black and white, there are numerous viewpoints between the two positions.

Speaking for myself, I lean toward the former, particularly since forced feminization is a classic theme in TG literature. The reader understands that the situation is pure fantasy and that the author does not advocate coercion in the real world. The same rationale could be applied to Aesop's Fables, Grimm's Fairy Tales or Greek Mythology. All of them depict horrendous acts, such as cannibalism, mutilation and even child murder, but we don't ban them because they're just stories at the end of the day.
