@igm,
I know very little about Buddhism so I don't think it is appropriate for me to comment. It seems likely that some eastern ideas were reaching the areas where Christianity arose and developed.
The notion that Buddhism might replace Christianity in the west seems more than a little fanciful to me.
It may well be remiss of me but I cannot help feeling that the sporadic appearance of Buddhism in the west is something of an affectation and were it to become more than that we should all be the worse for it.
I have a boundless admiration for the achievements of Christian society which can only be undermined if the eventual outcome was a wrecking of the social environment. The idea that we might wreck the environment itself seems to me to be grossly arrogant and not something evolutionists would feel comfortable even considering unless subjectivity caused them to take off their scientific hat for a spell and start grunting: which cod evolutionists have a distinct propensity to do. Much to my amusement.
I can see Prof Dawkins trying to render respectable his being on his third wife in every syllable he utters. And I can see that those who fawn over them are likely to be eager to embrace it all. And the more there are of people with good reasons to reject the Christian moral teachings the more popular he ought to become. It amazes me, after taking in what I see and hear, that he has not yet been proclaimed Leader of the Western World and that those who are leaders take some pains to be seen in church from time to time.
One senses that there must be some significant reservations about his spiel in the broad mass of the population.
I've met cod socialists a good few times. I suppose there must be cod Buddhists. One who, say, would convert to the Cicero Bible Church, on the instant, were the drop dead gorgeous only child of wealthy fundamentalist evangelicals to make sheep's eyes at one across a crowded room.
I knew a long time communist militant who used his compensation for being made redundant to start a business. He was very successful and within three years was treating his staff like Bradley Hardacre did in Brass. Had a gardener to tend his grounds. On the minimum wage of course.
Obviously I admit there are cod Christians.
