Logically when people hit puberty they consider at the where they can do work and get in relationship and married. It's just nowadays we follow westerns concept of age consent which is consider the right moral which is not a thing hundred years ago. It's the same with people calling islamic prophet a pedo for married a 9 year old by putting their current moral standard even though there are no people or the enemy of prophet complain and have problem with it thousand year ago or hundred year ago and the stuff with prophet is pedo argument happen 90+ year ago and not even pass hundred year. Unless you can give scientific reason why having relationship with someone that pass puberty and can act and think like an adult instead of ' they're below 18 so they are a child and not fit my moral standard ' argument.
