I think it would be a mistake to confuse protestant fundamentalism with political conservatism and Calvinism. Most fundamentalists I know are, indeed, political conservatives, but they are conservatives in the same sort of sense that many Catholics are; they simply want as little government in their lives as reasonably possible. Many, if not most, are also resistant to the commercialism with which business attempts to seduce us.
It is interesting to re-read the Social Encyclicals in times like these. Without going into them in detail, one of the fundamental bases is the spiritual autonomy of the family and non-interference with its internal dynamics and faith journey. Nowadays, (as even in Pope Leo XIII’s time) the marketing of exterior philosophies and mores is intense. Big government and big business are sometimes at odds in this, and are sometimes in league. But extreme intrusion of either into the lives of individuals and families is the natural tendency of both, and tends to replace the spiritual values we might otherwise have with those that such “parties in interest” want us to have; dependency, consumerism, moral libertarianism, and so on.
So, as Flannery O’Connor observed, Fundamentalists, at least Southern Fundamentalists, are closer to Catholicism (and in more ways than that) than they are to classic Protestantism, and would be surprised, in the main, if they knew it. I know more of them that I know Catholics because of the region in which I live, and most are truly earnest and God-fearing people. Most are not what I would call “Calvinist” at all; their main focus being on “being close to Jesus”, and are quite aware of their own inability to impose their decrees on God (unlike Calvin). We should not dismiss to airily their objective to “accept Jesus Christ as my personal Lord and Savior”. There is more to that than just words. Inasmuch as the Eucharist is, indeed, that which they unknowingly seek, I am inclined to agree with O’Connor, who opined that eventually the greatest missionary territory for Catholicism in the U.S. would be the American South. To that extent, then, “muddling” of Catholicism and protestant fundamentalism (at least of the Southern variety…I can’t speak for the north) may actually be a good thing. In my own parish, for example, our numbers increase by approximately 5% per year due to conversions, largely from protestant fundamentalism. Virtually every one of them cites their realization that the Eucharist is, indeed, “being close to Jesus” in the most powerful way that can be achieved on this earth.
One is right to be wary of media personalities of all kinds. It needs, however, to be realized that evangelical television personalities are not particularly representative of protestant fundamentalists. They make many compromises in achieving their fame, just as politicians do.
Vegans can definitely be on the verge of neo-paganism, and I have known some who, to me, seem to have already gone over the edge. But it isn’t necessarily the case, and I did not intend to imply that it’s a universal or even majority condition. I do get just a bit wary, though, when vegans begin declaring meat-eating sinful, just as I would be wary of someone who declared veganism (is that the right word?) sinful. Neither is sinful, but the reasons why we might be either one could infuse sinfulness into what is otherwise a morally neutral thing.
