I personally agree,Communication begins when the sender of a message encodes the message. This means the sender translates his or her thoughts and feelings into words, gestures, facial expressions, and so on. The sender then transmits the encoded message by writing, speaking, or other personal contact. If communication works properly, the intended audience receives the message and is able to decode, or interpret, it correctly. Of course, mistakes do occur.
In the majority of cases, a speaker is espousing his/her beliefs, and, for the most part, being paid to do so. Although I'm not very trusting of politicians, they do pander to their audiences. These speakers employ half-truths, deceptions, and all manner of nonsense to achieve certain ends. ALL speakers must be held accountable for their message.
A message cannot stand on its own merits - the speaker is it's amplifier. Anyone could read a script, and indeed many people do read scripted public statements all the time that they never personally penned, but when we hear an original idea coming form the author's mouth it gains credence simply because more work was put into it. If we took disassociation to the logical extreme then something as grandiose as religious texts with familiar religious icons would be pointless - or in other words...why would Jesus matter?
If we disassociated the message from the speaker, then what is the point of listening to them? It means you don't take them serious. Some people do mix up their message, but you can usually tell that the person was struggling with what they were trying to say. That is when you give them the benefit of the doubt if you like what they are trying to say. If you do not like what they are trying to say, one might ask them to give a clarification to their message.
I don't feel that we should separate the message from the speaker. As an example, a lot of people are willing to forgive celebrities if they say something really outlandish, racist, or bigoted. We need to realize that what people say is a reflection of who they really are. We sometimes use this as an excuse because we really like someone and don't want to stop buying their albums, or whatever. But we should hold people accountable for what they say.
