I think there are lots of dialects because it's the easiest programming language to misunderstand.
Somehow, someone who makes a scripting language with C syntax , like Awk or Javascript, instinctively knows that it isn't C and not to call it that.

That sounds about right. It's very easy to make something resembling a Lisp, and even easier to call the result a Lisp.
Anyone who is interested in the design of prgramming languages will find it easy to make their own Lisp and try out any ideas that seem congenial to them. The natural and obvious consequence is a lot of Lisps.
