What do you make of all these businesses with their "no kids allowed" policies (or
Brat Bans)? Personally, I think it's about time. Children are given more priority than is reasonable, whether it's for commercial appeal (such as with the entertainment industry) or enforcing counterproductive public policies (such as the War on Drugs).
Owners of privately owned property should free to establish no-child policies in the use of their property.
