First a definition: Pathological – deviating from normal, healthy, or efficient
Next some considerations of pathology in the context of evolution and society:
Evolution – The proper purpose of behavior in evolutionary understanding is to maximize the survival likelihood of the individual, the genetic line of the individual, and the species of which the individual is a member. There may be many ways to accomplish these ends but of course the ones to be preferred are those that are most efficient since individuals have limited life spans and resources.
From the definition provided above we can see that an individual who is not acting toward the named purposes in efficient ways is pathological from an evolutionary standpoint.
Society – Generally speaking societal behaviors or norms that are preserved in nearly all societies over nearly all times are evolutionarily favorable (and probably evolutionarily directed). Thus such things as family closeness, clannishness, community cooperation, patriotism, traditions, belief systems, and so on are likely to be positive, evolutionary survival behaviors since they can all provide a measure of security, and support that enhances survivability.
Once again, we can conclude that individuals who go outside these lines would fit the definition of ‘pathological’ since they place themselves not only out of the norms but may imperil their own survival by losing the support of community, family, etc.
If my reasoning is right then, I think we may safely conclude that we deconverts are pathological.
