Smug? Or just dumb?

Lispers are the most ignorant people I've ever seen online.

They have no idea what they're talking about, but think that advocating Lisp and mentioning SICP gives them a facade of authority and disguises their ignorance.

They are not only too ignorant to know how ignorant they are, but smug about it.

Haskellers are the most ignorant people I've ever seen online.

They have no idea what they're talking about, but think that advocating Haskell and mentioning Homotopy Type Theory gives them a facade of authority and disguises their ignorance.

They are not only too ignorant to know how ignorant they are, but smug about it.
