Yes child porn is sinful, but it is not an issue for the State hypocrites. Check into 'pizzagate' for the truly vile crimes of the high and mighty being kept hidden by the MSM.
Given that the Jewish and Christian communities of the time that the Bible was being complied allowed Marriage at an age most if not all USA States declare to be against Caesar's Law I take the position that the State is inserting itself into an area where it does not belong. Mis-behaving teens is something to be resolved between families, NOt by the State- a State which BTW, in its schools openly encourages sexual experimentation and then gets all righteous and judgemental when teens share pic on those IPhones they should not have in any case.
What we have here is the State as usual creating a Problem so that those cells in the private prisons can be kept filled and the politicians can keep getting campaign funds from the prison owners.
