Kids not knowing about sexuality and therefor the absolute basics of consent only helps child abusers, and the earlier you ingrain the concept of consent, the better off they will be later in life.

Basic knowledge about this thematic complex has to be introduced in the first few school years to make sure they

• know when somethings iffy, because all child abusers tell their victims that this is ok and completely normal
• know who to talk to in case of abuse, which must per definition include basic knowledge of what abuse entails in age-adapted language.

Hiding these basic facts about life itself only makes bigots feel better and child abusers very happy.
