Sex trafficking in the USA hits close to home
See I know personally a couple that works to rescue these women and girls in New Orleans. I know their M.O. I know how they get their victims and I know it's a HUGE problem in this country.
Aside from the traffickers, if you don't believe there are enough perverts out there to warrant concern you're deluded. Ask the folks in Cleveland, or the family in Iowa, or West Philly.
In my opinion ONE is too many, and given the skill with which the government has handled health care so far, the IRS, our privacy, Benghazi, etc. you can bet they're going to do a bang-up job being parents, too. Me, I'd rather let parents do the job.
