A general definition from good old Wicked Pedia.
LOL, that looks a little messy. Despite that, we’re in agreement to the original meaning of the word. I still think it has been bastardized by today’s media, and its use against Conservative is inexcusable. (along the lines of it’s substitution for ‘terrorist’) And I would add, even in its proper context as well.
Even within a Constitutional environment, open dissent is deemed healthy, not a threat. The use of this word was out of context in the extreme IMO.
