My point: You say that I am a child abuser and that I possess child pornography. I am giving you a chance to get me arrested, tried and put in prison.
You are refusing to take that opportunity, meaning either you're lying or you have no problem with child abuse and child pornography.
My offer stands- any time you want to report me to the FBI for having child pornography, I will give you my contact info in private. (This offer is open to anyone.)
Of course, you could just admit I don't actually have child porn and I'm not actually abusing my child and that's why you are refusing to report me...
Nope, my argument is that you won't do anything about it, therefore you think it's okay.
You know how to get my info to report me to the FBI if that's what you believe. You refuse to do it. There can only be two reasons, unless you're going to lie and claim that the FBI never arrests people for possession of child pornography.
