Meddlers and Busybodies.

1 Peter 4:15 (NASB)
Make sure that none of you suffers as a murderer, or thief, or evildoer, or a troublesome meddler...

1 Peter 4:15 (Wuest Expanded Translation)
Let no one of you continue to be suffering [reproach] as a murderer or a thief or an evildoer or as a self-appointed overseer of other men’s matters...

Two points:

1) In the Church, busybodies are the functional equivalent of murderers and thieves. 

2) In an era of mass media and partisan politics, being a "self-appointed overseer of other men's matters" is the most common type of "public Christian."  In other words, this is, to our shame, what non-Christians think that Christians are like. And it is a problem on the Left and on the Right.

And I just did the same thing.
