Debate Guide: The kids do not want it
"Your arguments will only come into play, once children themselves start asking for sex. I have not heard a single one making such requests!"
And the female half of Saudi Arabia aren't shouting from the rooftops for equal rights either! Why? Both them and western children have been excluded and alienated from the civil rights discourse. The very definition of oppression is to undermine liberties with physical or mental tyranny. Very few groups as large as legal minors, women (in some countries) or slaves would be suppressed if they stood up and challenged their mistreatment.
This remains largely irrelevant, though. I am advocating freedoms, so firstly I do not need someone's explicit will to act, in justifying law reform. Even if I did, I could refer to lists of accounts and Studies to back myself up. On the other hand, you are advocating coercion (from sex). So unless the consensus in lawmaking has shifted from "what should we prohibit?" to "what should we allow?", it is you who requires evidence of widespread dislike of sexual activity among children, for your arguments to be realistically considered.
Needless to say, if you were to neutrally poll children on their sexual freedoms, you would have to drop scare phrases such as "rape" and "molestation" to get them to agree with you. Remember, the current social situation (withholding of information, scare tactics) has conspired as not to lead children into actively demanding their sexual freedoms without prompting. Very few children have a concept of civil rights or activism, nor do they have the right to vote. Due to society's wishful denial of children's sexual appeal, youth are not driven to see themselves as sexually attractive and thus eligible. There is no way of asking for something that you are not even allowed to comprehend the existence of.
