bjc,
I think the "spirit with which I am asking" and the spirit with which he is telling should both be looked at. I am trying to remain rational and ask what I consider to be reasonable questions. He has been angry and insulting. I am not trying to "stump" anyone, I think, however, he wants to "stump" us, so now where does that leave us?
Regarding "humility", I think in this kind of situation, that humility should be a two way street. If I espoused certain beliefs, should mds humbly except them? I think not, and I don't think he ever would. Would you?
