Modern Churchianity replaces "love your neighbor as yourself" with "love your neighbor, hate yourself." John C. Calhoun explains here why categorical disregard for oneself must produce chaos, in the same way that pure selfishness would:
"In beings of limited reason and faculties, ... if their feelings and affections were stronger for others than for themselves, or even as strong, the necessary result would seem to be, that all individuality would be lost; and boundless and remediless disorder and confusion would ensue. For each, at the same moment, intensely participating in all the conflicting emotions of those around him, would, of course, forget himself and all that concerned him immediately, in his officious intermeddling with the affairs of all others; which, from his limited reason and faculties, he could neither properly understand nor manage. Such a state of things would, as far as we can see, lead to endless disorder and confusion, not less destructive to our race than a state of anarchy."
So, hating yourself is essentially equivalent to hating your neighbor, as the outcome is the same.
