Exactly. You can accurately say "evolution isn’t controversial in the scientific community" (with a qualification), but you can't accurately say "evolution is completely uncontroversial [full stop]" (unqualified).

A course-grained "controversial" tag will either apply very broadly or be inaccurately used (out of parochialism or other bias).
