What don people understand about the difference between the fiddle and the violin?
It’s discourteous to call people “spineless worms,” but having objected to that, your assertions are not entirely accurate. While violin type instruments originate from multiple sources, in modern parlance, what you’re saying doesn’t reflect contemporary scholarship. The instrument contemporarily known as a “fiddle” does not originate from the sources you claim, but was developed along exactly similar lines as that of the violin, used in art music.
