Here I attempt to answer these questions with what I hope any critical thinker can pick apart
For me 'critical thinker' sounds FAR too much like 'CRITICAL THEORY', one of the favorite Marxist doctrines found in the BLM and other Communist enablers. A tenet / tool of the 1930s Frankfurt School (Germany), it has the same characteristics of the terms you have cited, that of multisyllabic definitions that appear to more obscure than enlighten.
Critical Thinking predates this, critical theory only hijacked it like the left does to all language.
