I disagree. As Marshall McLuhan said, "the medium is the message." Poorly delivered messages are prone to be lost as noise.

This critique is one of rhetoric - which is not what McLuhan meant in the concept contained in that quote at all.

Your complaint seems to be that the use of a sexual metaphor affects the ethos of the speaker in the eyes of some.

That metaphor is part of the message, regardless of whether or not you like it.
