You knew there had to be one! And it isn't too far into the book that one finds it.
Mr. Dreher sets out to tell us that a Crunchy Con is an anti-materialist, not involved with bigger and better and the acquisition of more and different things. Then, in the first two chapters of his book he talks about food and homes. Admittedly it isn't about acquisition so much as it is about how to "do it properly," but the end result is an almost obsessive concern about how you get your food and what kind of house you live in.
It would be ridiculous to say that these are of no importance--they do affect how we live and how we feel. However, they are not the end-all, be-all, nor do they necessarily dictate how we relate to one another. If one buys one's food at a supermarket, one could still hold the values that place people and relationships above things. And yet, there is a sense in which it does not seem that Mr. Dreher thinks this possible.
One final point, in the discussion of homes, it is evident that Mr. Dreher thinks that if you don't live in a gentrified inner city or in a rural setting you simply aren't living anywhere that is livable. There is a constant denigration of the way that most people must live. Calling suburban house "McMansions," etc.
Because the book is a first stab at the articulation of a principle, this is probably the fallout of attempting to define a concept. What would be more helpful is to say how one could modify the mode of life one is in without pulling up stakes and moving to the inner city. I think in food Mr. Dreher makes some useful suggestions about how we might alter the way we live--but he fails utterly at making accommodation for present circumstances in the section he calls "Homes." And more to the original point, it seems to be overly concerned with material objects. Our homes are important--but I have discovered during the extended absence of this summer that home is not a place or a building, it is the gathering of the people you love deeply. My home is wherever Linda and Samuel are.
