Greatest political theory - The BRTD Effect
It's not even really a theory anymore; it's fact.
Not to be all persnickety, but by the scientific definition of "theory," you do treat it as a de facto fact. (More accurately, you assume that it is true until there becomes reasonable evidence that it may not be)
"Realignment theory" is sort of a broad term. What, specifically, are we talking?
Yes, a common misconception of language. Many people confuse a "theory" (which is an idea backed up by scientific evidence, though not yet to the extent that it can be determined to be true for certain) with a "hypothesis" (one that, while possibly sounding logical, has not yet been tested scientifically). A "law" of course is an idea that has been proven to be true beyond all scientific doubt through rigorous testing.
So for example when people say evolution is "just a theory" they seem to think that means it's not supported by any evidence.
Yes, it annoys me as well. That reminds me:
