I never said that I think (organized) religion can do no good - I simply said that (off hand) I cannot think of any examples of that.
The many dozens of people who have ascribed all kinds of examples of goodness and lumped them all to the credit of some organized religious group or other (Lutheran, Roman Catholic or whatever), forget one or two things: Charity emanating from organized religion ALWAYS has strings attached ("I will give you food/education/shelter/clothing, but first you must convert to my religion"...) plus the plain fact is that many of these good acts stem from innate human (slash/animal) kindness, which surely does NOT need any organized religion to reconfirm its validity.
As to the arts (yes, the Sixtine Chapel, Brunelleschi's Dome in Florence, etc., etc.) were all CO-inspired by religion (the only one in town, by the way...), but also very much by civic pride of the various guilds, towns, governments (bit like recent corporate efforts to build themselves the highest skyscrapers).
Finally, how about a thorough study how Europe became christianized - We were taught in school that this was a beneficial and wonderful thing (yes I was brought up Dutch protestant), but on closer inspection it is clear that Willibrord, Boniface, and all their ilk made their religious "conquests" generally by FIRE & SWORD. "Either you, the chieftain, become Christian, like me, or this army standing behind me will rape, pillage, burn and exterminate all of you! No-brainer, really, isn't it? (Mr Frisian, Batavian, etc etc).
May the debate progress! Maybe, this way we will all of us find "the solution" to this problem (the dominance of organized mass-religions in this world).....or maybe not!
