I turned out to be a White Knight, which sounds dreadfully heroic and naïve. When I got to the part about being like the Crusader Rabbit, I was a bit more disturbed (I do battle with Texans?) The last couple sentences made sense to me, though:
You are the anonymous philanthropist who shares your wealth, your time, and your life with others. To give is its own reward and as a White Knight you seek no other. On the positive side you are merciful, sympathetic, helpful, giving, and heroic. On the negative side you may be impulsively decisive, sentimental and misdirected.
I think some of those positive characteristics do describe me (although I'm a bit more selfish than they'd imply), and the "impulsively decisive" is definitely true...just ask jcobleigh how often I go off tilting at windmills!
