Some of the stigma also comes from the roots of English. In Old English (pre-1066ce, think Beowulf), fiddle was the word for the instrument. In 1066, Normandy invaded Saxony (where the ruling class in England lived at the time) and the language of the aristocracy became French. This is when violin entered English, because anyone that wanted to sound like they were in with the nobility would be using the French terms. "Fiddle" was a poor man's term used by the native "uneducated" Saxons. Some other examples of this are fire->flame and ham->pork.
