I did not say they did. But Hotels do ask about the number of guest and whether there are children. A room with a child in it should not be able to access porn. Unless you want to repeal the laws which prohibit distributing porn to children. In that case you are probably a libertarian who wants to repeal all drug laws and such, which we will disagree on.
Drug prohibition, nah go ahead and enjoy your taxes being used to enforce a blackmarket monopoly that makes men like Pablo Escobar rich, fills our prisons so that there's not enough room to keep pedophiles incarcerated, promotes violence and funds the Taliban. It's only been going on for 30 years and has been wildly successful in preventing drug abuse. We don't need that tax money for the WOT or social security or border defense.
