Here’s a little analogy: I’ve been composing electronic music for 35 years now, and some people still think it’s just a matter of pressing buttons, that it’s easy, that anyone can do it the same way, that I do this because I don’t have what it takes to learn to play a “real instrument” and that I’m not a “real musician”.

You get used to it, and eventually you stop caring. Too bad for them if they’re more interested in the process than in the work itself.
