The above question is equivalent to Conservatives asking why “Leftists” tend to “harp on slavery and Jim Crow”. After all (the “reasoning” goes): it’s 2016, and nobody — not even the KKK and other (openly) “White Supremacist” groups — are in any kind of position to actively enforce a return to Slavery/Jim Crow, even if they wanted to do so.
The answer is two-fold:
- Those who fail to learn from history are doomed to repeat it.
- Orwell’s “Memory hole” exists in real life.
There is a definite impetus both among self-identified Christian “laity”, and among the “clergy” of various Denominations to hand-wave away inconvenient facts related to the “Christianization” of Europe (at sword-point), the suppression of purported “heresy” by means of torture/slaughter of “heretics”, etc. Even the cuddly-fuzzy “NALT”-types do it, to some degree. The mere fact that they essentially disavow centuries of “Christian” history so as to better market their warm-fuzzy, “Affirming” variant tacitly requires that their intended audience evade the fact that “Christianity” floated to historical prominence on an ocean of blood — the blood of “unbelievers”, and “heretics” alike.
THIS is the essential problem with (most) Fundie Protestants: they are completely ignorant of the history of what they claim to “believe”.
Here’s the thing: nobody “believes” in a vacuum. Typically, the (purported) “Salvation” experience takes place within a very specific context — which could be as simple as: an individual, experiencing a serious personal crisis in their individual life, being “pressure-sold” on some variant of “Christianity” — at a point where that individual is incapable — either emotionally or intellectually — of UNDERSTANDING what they now claim to ‘believe”.
In other words — even from an explicitly Christian frame of reference — the Fundie animus on “feel it in your heart”/”Simple faith”, etc. necessarily leaves (so-called) “Young Christians” utterly defenseless against “false teachers” intent on “tickling their ears” with “unsound doctrine”.
I am INCAPABLE of the level of stupidity required in not actually attempting to LEARN ABOUT SOMETHING WHICH I CLAIM to “believe”.
I am also utterly unpersuaded by “personal testimony” about the “personal relationship” they supposedly “feel in their heart”. Y’know why? Wesley Willis had a very “Personal relationship” with his “Hell-ride Demons”.
What is equally galling is the fact that the myriad of “Christians” wandering around, intent on shoving their “Great Commission” down everyone else’s throats at the first opportunity — all regard one another as doctrinally corrupt.
(Witness, for example, the seething contempt directed toward “Jehovah’s Witnesses” and Mormons.)
So, no. I am also not going to restrict my inquiries to any one line of organizational agitprop. (For example: JW’s explicitly “warn” their members against even inadvertently exposing themselves to the “ear-tickling”, from other Denominations/sects/cults.)
That’s the thing: the line between “Denomination” and “insular, ethnoreligious subculture really isn’t that sharp in most cases.
Hasidic Jews, Mennonites, Hutterites, Amish, etc…..but you get the idea.
Self-imposed isolation ensures that the self-segregated group will be ‘self-correcting”, in the long run, in that the resultant “inbreeding’ will eventually result in total physical — and cultural — degeneracy.
So, yeah: exclusionary subcultures eventually become inbred, and (given enough time) eventually become nonviable.
Etho-religious subcultures are, in this sense, both “self-limiting” and “self-correcting”.
Personally, I think that’s a good thing.
