In response to the OP, I don't know that I am sane. Society judges me as sane /insane, based on an objective view. I have a few really blunt trusted friends and my wife that I can ask anything and get their perspective. That's my checks and balance. I'm introspective enough to take gradual slight changes with a grain of salt, but still notice major shifts and use my "panel then". I also factor in a self judgement based off the range of people I observe (ie. I'm not nearly as bat-shit crazy as that guy or that is the most grounded person I've ever met). I usually fale somewhere inbetween, but closer to the side of rational and grounded in my circles.
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
