modern respectable opinion, even in venues like LW, is appalled at the idea that these aspects of human life -- which are in our society treated with an extreme level of both idealization and ideologization -- can be analyzed in such an undignified and desecrating but nevertheless correct way.

Actually, I think the question-begging turn here is in "correct." Perhaps the referenced ways of dissecting human relations are correct and perhaps they are not, but it does not seem to be the case that what the author refers to as "modern respectable opinon" (whether justly or unjustly) consider it to be so. Thus it does not seem that they are, in fact, appalled that "these aspects... can be analyzed in such an undignified and desecrating but nevertheless correct way."
