Sexual jealousy is a major factor in all aspects of life. The jealous harass those whom they perceive as more attractive. Parasites revel in destruction of entire types, using their hatred to advance socially while simultaneously encouraging other parasitic groups to join their envy fray. This is a fundamental reason parasitic ideologies flourish and attract followers even as they clearly make little or no sense. Academia is an example of a large American subculture infested with parasites who enjoy ruining things. Pleasure in destruction is a parasitic trait, a cultural trait of parasitic groups. You can identify them by this trait alone. Since sexual jealousy is such a deep source of hatred, it fuels parasitic groups as much as does greed and lust for power. ABN
