No, I get it. I have a Classical music degree and even though I haven't used it to pretty much anything, it still means I get annoyed at times. And yes, definitions are tricky. One of my relatives keep referring to Sarah Brightman as the best opera singer they know and I'm like...she's not an opera singer. She's classically trained and a soprano, yes, but she's not an opera singer. (And then they got mad at me because I was being deliberately nitpicky.)
