Biologically, it would appear that a minstrating 12 year old would be an adult. While most of us agree today they are not mature enough, what is to stop this from being the next barrier in the future? Same sex is a perversion of our natural state, yet it exist now. As perverted as it is to think of a 12 year old getting married, what's to stop this perversion in the future?
Nothing can stop perversion, because
all humans are perverts. Just truth asserting itself over myths.
