The demand for child sex is fueled by porn & fornication which in turn comes from decoupling sex from procreation, marriage, and family.
Ultimately, this has its source in idolatry and the rejection of God.
We're being shown in real-time the logical progression of liberalism. Rejection of Jesus -> Rejection of external divine authority and law -> acceptance of internal authority and do whatever I want -> acceptance of birth control -> sex is for fun -> acceptance of divorce -> acceptance of baby murder -> acceptance of child sex etc. etc. etc.
They deny the reproductive purpose, and divert it into mere "pleasure" which is unsatisfying and leads to greater abuses of the human powers of procreation.
Heck they are already into child sacrifice and Satanism . . .
all for pleasure? no all to be a god! unto oneself only beholden.
