Cable news is bad. Fox News is the worst. It is, after all, the network that blamed a hoodie for the death of Trayvon Martin and claimed that poor people have it pretty good if they’ve got a refrigerator. We’d all probably be better off if we shut off Sean Hannity and Megyn Kelly and watched sports or nature documentaries or talked to our families. This does not have to be a hypothetical. We have the technology in our very own homes to make this dream a reality.

Abby, a Slate reader, watched her mother—who’d lived in the United States as a permanent resident for nearly 30 years—become a U.S. citizen to vote for Hillary Clinton in the 2008 Democratic primary. She was quite surprised, then, to find her mother becoming an increasingly attentive Fox News viewer. Abby felt she had no choice: The child unleashed the power of parental lock on her own mother.

After Abby’s mother called her cable operator to ask why the channel wasn’t working, Abby revealed that she had blocked it. The mother and daughter then had the opportunity to “have a conversation about whether it was a good news source or not.”

If you see your friends or family falling into the chasm of cable news, perhaps parental lock is right for you. Here are instructions for three major cable providers, copied from those providers’ websites.

Time Warner instructions to “monitor your kids’ entertainment”:

Press the Settings button on your remote. Select the Parental Controls category. Select the Content Block category. Search for the content that you wish to block and press Select. The content category to be blocked will display in the list with a Locked icon. Enter your PIN. (The default PIN is set by each local TWC Store, typically 0000.) Press the C button to save your options.

Comcast Xfinity instructions to “lock access to specific individual channels” for boxes that use the X1 operating system:

Press the left arrow button once to highlight the logo and channel number of the channel you wish to lock. Press the OK button. Using the right arrow button, highlight Lock. Press the OK button. If you have already set up a Parental Controls PIN, you will be prompted to enter your four-digit Locks PIN using the number pad on your remote control before you can continue. Enter the Locks PIN a second time to confirm the channel lock.

Comcast Xfinity instructions to “control what your child watches” on non-X1 TV boxes:

Press the Menu button on your remote twice. Highlight the Parental Control feature on the screen. Press OK/Select and follow the on-screen instructions.
