To an extent it was a rhetorical question. I have two views. Firstly the human tendency to pidgeon hole people or stereotype as you say. I can understand this, but stereotyping seems a bit strange coming out of a community considered by the world at large to perverted deviants who need their heads testing.
Secodly the view I came across on another thread that you can't be good at two things. The problem with that is there are many cases of people excelling in more than one field and also, if true so what. What's the problem if you enjoy playing the guitar as a pasttime but ain't very good at.
The confusion theory irks me a bit. Makes me feel like the "perverts" consideri me perverse ha ha.
PS - nobody disputed my comment that it was the the general view, I expected 'never heard anyone say that' responses.
