You would really have to know more about what happened to say w/o a doubt that this was rape. Lets say the little girl (14yo is still a child) was having sex with some older boys maybe letting them all take turns having sex with her. Little Chris Brown is curious and the older boys ask her if he can stick it in too. She says yes, little Chris Brown sticks it in plays around and leaves feeling a like a little man. This is NOT rape. Sex play is very common between children & w/o appropriate levels of adult supervision children can engage in a level of sexual activity that is not healthy for their age. The real issue with the story is lack of parental guidance. Kids that age shouldn't easily have that much access to porn and a 14yo girl should not be having sex with random neighborhood boys.
Unless, this guy has the details on who initiated the sexual contact and how everything happened (which he clearly doesn't) he has no basis to claim Chris was raped. This statement that a child can never consent to sexual interaction with another child is dumb. It completely ignores the reality that children can be sexually precocious at young ages and if given the opportunity they will experiment with other children and imitate behaviors of older children. Throwing around the word rape is unecessary and destructive. Now this little 14yo girl who may have been peer-pressured into having sex w/ Chris by older boys is being tabled a "rapist". It's incredibly dangerous to make blanket accusations w/o having all of the facts.
