Codeborg/tcis: I've had a few discussions with Frank on this subject, and while I've rarely(if ever) had a problem with his language, other people are quite frequently on the receiving end. I think it happens as a result of his experience.
He has heard most of these arguments many times before, and as such is exasperated by them, which leads to his being abrupt with "newbies". Then, when they respond to this perceived slight in an insulting manner, he responds in kind twice as hard, which makes people even more upset.
I personally think he could stand to tone himself down, but I completely understand why he thinks he shouldn't have to.
As far as the actual topic of this thread goes: speaking as another agnostic, I would say that "word games" isn't what agnosticism is about. Someone earlier made the point about probability, which I think is true: you can have opinions, and lean towards one side or another, and still be an agnostic, but the difference, I think, lies in theists/atheists' unwillingness to admit that their beliefs are based on guesswork/probability, and profession that they "know" one way or another.
I personally think there is slightly more evidence substantiating the position that God
does exist...but only by a small, highly unreliable margin, so I remain in the neutral category of the agnostic(with a leaning, though). While I cannot say this with any definite ability, I think Frank has just collected so much information about both sides that they balance out in his mind, and he truly
is in the middle.
Once people know how to discuss things with him, I think that they find he is very interesting...unfortunately, it's hard to do that unless you already agree with him.
That's my explanation of Frank; anyone else have something to add? Also, why exactly was Frank kicked off? That's no good.
