Demonrats are suicidal by nature - they embrace everything evil & harmful.

Not to mention the fact that they're anti-breeding themselves out of existence due to their convincing themselves, & any spawn unlucky enough to emerge from one of their polluted wombs, that they're the opposite sex or some combination of sexes, and to immediately mutilate and/or remove their sexual organs.

Their numbers diminish naturally & inevitably via intentional self-destruction - this is why they recruit, and need the schools to refresh their ranks.
