The combination of sexually aggressive dress with deliberate uglification (tattoos, hair dye, facial piercings, etc.) is telling. The goal is specifically sexual attractiveness without beauty — attraction stripped of its aesthetic, spiritual, human aspects and reduced to raw animal lust.

Thus Wm. Jas., in a discussion with Bruce Charlton

Never forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on the Enemy’s ground. I know we have won many a soul through pleasure.

All the same, it is His invention, not ours. He made the pleasures: all our research so far has not enabled us to produce one. Hence we always try to work away from the natural condition of any pleasure to that in which it is least natural, least redolent of its Maker, and least pleasurable. An ever increasing craving for an ever diminishing pleasure is the formula. It is more certain; and it’s better style. To get the man’s souls and give him nothing in return — that is what really gladdens Our Father’s Heart.
