What leads you to believe there's "no good reason"?
I'd have to say that if you're espousing ideas like "there's no such thing as mental illness" and "there has been no very convincing study on the harmful effects of smoking," then there are perfectly good reasons to conclude that insulting those who disagree with you is unreasonable - both of those are distinctly unorthodox ideas, at least in the modern world.
Whereas, the fact that Elton John's re-working of the song "Candle in the Wind" was vomit-inducing was, and is, perfectly evident to anyone who heard it or saw it. So, this might conceivably open you up to accusations of trying to associate your unorthodox ideas with your orthodox one(s), so as to legitimize them in a reflective sort of way.
