That is not the proper use of the medical term “bipolar”
FJP: Actually, if we appended “Disorder” or “Affective Disorder” to actually make it a “medical term”, you might be right. However, we’re going with:
bi·po·lar, adjective. 1. having two poles, as the earth. 2. of, pertaining to, or found at both polar regions. 3. characterized by opposite extremes, as two conflicting political philosophies.
So, we’ll grant you a loaded word, but not a misused word.
