Not a bad analogy, the shouting. I'd have compared it to walking around naked in front of an open window and then complaining when people see you in the buff.
If you don't want to be seen naked 1) put on clothing or 2) draw the shade. If you don't want your publically transmitted data to be understood, turn on the encryption in your router. Don't know how to do that? 1) RTFM, 2) ask a friend for help, or 3) don't use technology you don't know squat about.
