Uh, paedophillia is statistically significant. The wider issue of child abuse (physical, emotional, sexual abuse or neglect) means that about 5 children a day die in the US from abuse-related causes.
Numbers are difficult, but over 3 million reports (for over 6 million children) are made every year in the US, and about 9% will be for sexual abuse. (And about 90% of those will be where a child knows the offender in some way.)
Very many people are harmed, sometimes severely, by paedophiles.
Please don't ever place paedophilia in the same category as 'nonsense boogeymen' like terrorism.
