So we know that fanatic purifiers will automatically purge all xenos within their borders, but what purge type should be chosen. For reference (I've removed displacement since it isn't allowed by the civic)
- Extermination: The species is systemically killed off by any means available. This is the fastest form of purging, but pops subject to it are unable to produce any resources while they are busy dying off.
- Forced Labor: The species is placed in camps and forced to do hard labor under brutal conditions with inadequate food and shelter, effectively working them to death. Pops doing Forced Labor will be killed off more slowly than through extermination, but will continue to produce minerals, food and (at a significant penalty) energy.
- Processing: The species is processed into food for the consumption of other Pops. Pops being Processed generate a fixed amount of food and die off at a fairly fast pace, but cannot be put to use producing any other resources.
- Neutering: The species is prevented from reproducing through chemical castration or biological modification, eventually dying off naturally. Neutered Pops continue to function normally and may even be given a high standard of life, but have a large penalty to their happiness. The speed at which they die off varies based on the species' natural lifespan, but is typically very slow.
