Those terms are so frequently conflated these days, especially by groups who are addicted to their "side". They want to paint any middle ground as pure idiocy, in order to corral people in to the 2 camps. Divide and conquer in action, by simply conflating two English language terms in to one with enough repetition that it enters the zeitgeist. Reddit's /r/enlightenedcentrism is a perfect example of this type of manipulative propaganda. That sub's entire purpose is to conflate the status quo with centrists, as if centrists cannot ask for change, or as if there is no such thing as a historical centrist. It's pure propaganda, that eliminates the shades of grey that actually make things interesting. Instead we are controlled, and offered 2 awful choices which are both owned by big money, leaving us with no actual representation.
