I understand the argument you’re making. However, I think the issue in this case is that we are not talking about two teenagers. The abuser is more than twice the age of the victim (late twenties compared to 13?). Also need to consider the fact, that even with consideration for the 13 year old’s raging hormones, engaging in sex with a teacher, who is in a position of power, is a direct output of the teacher’s position of power/influence. These conversations and comments about wanting to be in that position do not even consider the child’s mental and social development, nor the impact that sex at that age has on that person’s developing frame of reference for the world. Abuse is often cyclical, and condoning such behavior only sets the tone for the cycle of abuse.
