You better get used to learning unless you can raise your kids far far off the grid (then you have other issues)
Going to put your kids in sports? Church youth groups? Martial arts? Music lessons? Let them go to a park to play? Spend the night with a friend? Have a backyard neighborhood barbeque? Send them to college?
Think none of the 2% lurk there?
Vigilance. My kids were never alone with any adult until they were over 14 years of age and had been well schooled in who is a deviant and who is not.
