Parasitic behavior represents a reaction to a weakness within the host. They suggest by choice; we consent by choice. That's the weakness of ignoring to use choice in reaction to balance, to instead submit to the suggested choices of others. This choice of ignorance is what tempts others to use suggestion to parasitically exploit it, and ignorance also tempts insolence towards the ignorant; because they rather blame others (calling them parasites) then to question their own choice of ignorance.

Notice how the parasitic few both suggest the many to blame each other; while also utilizing blame directed at themselves for protection by claiming persecution?
