Communication: why is this such an emotive subject?

Abstract

Communication is the activity of conveying meaningful information. Communication requires a sender, a message and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the sender.
