"I am sure you can disable porn channels in your hotel room. You can't just access it without paying first. "
Actually, most of the porn channels in hotel rooms have previews. Those are accessible by anyone with the remote, and without paying. It's a good idea to ask the desk to shut off all access to adult channels when you check in. They can, and will, do that for you.
The previews are pretty lurid...not what you want your kid viewing while you're out of the room.
Why would an atheist care if their kid watched porn or not?
