Honestly, I don't care what you choose to call it. Our world warrants us certain freedoms, and how we use those freedoms will set the stage for the future world. As you've said, CP implies consent. If you would like to spread the implication that these children somehow consented to be part of this sexual abuse material, then keep calling it CP. I, with the rest of those who wish to not spread the lie that they consented, will call it CSAM.
