I am trying to think of a word used to describe someone who is intentionally oversimplifying an argument by making a statement that is technically true, but ignores a lot of issues. Its an adjective similar to describing the person as being intentionally obtuse or too clever for their own good.
I might go with "glib" as a synonym for "superficial." However, neither of those are really about being too clever.
When I think of "too clever," I think of "cocky" of "flip."
