A young adolescent who has a poor family upbringing and becomes the prey of a homosexual does not "choose" to (as you put it) "either actively participate or not to actively resist". A MINOR adolescent is not expected to, nor should be expected to, be able to protect themselves from the predators of the world. Parents, teachers, and society are supposed to do the protecting, not the predating.
We are not saying the same thing.
What part of "preying on weakness" do you not understand?
I know...because it happened to me. A religious brother who taught art class at my junior high school put the moves on me. Faced with a similar situation, I simply said, "Brother, please don't try to hug me and stuff, that makes me feel uncomfortable." ...and then I went home and told my mom.
The next week, in art class, I told the religious that I had told my parents that while I liked art class, I felt uncomfortable with his attempt to "hug" me. At my mother's instruction, I told him "My mother told me just to tell you how uncomfortable it makes me and that if I feel uncomfortable again, I will be telling my parents."
Needless to say, we never had to deal with that issue again.
I was thirteen. My father was generally absent. I knew exactly what was going on. Don't underestimate the understanding of a kid.
