The Ultimate Act Of Utilitarianism

Utilitarianism deviates from logic at its first step.  By its very nature, morality, if it exists, is about what people are obligated to do even if they wished otherwise.  It is not primarily about achieving certain practical goals.  Indeed, sometimes an obligation to do or not do something might be objectively inconvenient for a person's subjective whims, even if there are plenty of ways to be both pragmatic and morally upright within a system of ethics like the Bible's.  Something immoral will not be made permissible or obligatory just because it could lead to practical gain and something obligatory will not be rendered morally optional just because it is difficult or inconvenient.

Again, a utilitarian moral framework is logically invalid from the beginning.  However, almost no one seems to truly understand what purely pragmatic societies would look like.  If the kind of utilitarianism in question is one aimed at creating a "utopian" society, there is but one way to force a culture into at least the external mold of rationalism--the only philosophy that is both true and intrinsically necessary to maintain a society's flourishing intentionally--although actions can never coerce a person's actual beliefs or force their allegiance to reason.  Many utilitarians want to selectively enforce conceptually mistaken pragmatist ideas of morality without ever realizing the most utilitarian idea of all is one they would almost certainly never entertain.

The ultimate act of utilitarianism is the systematic killing of all non-rationalists other than young children and those with psychological disabilities that might prevent them from developing the same level of intelligence as a psychologically stable rationalist.  Almost every solvable moral, political, and practical problem facing humanity that can be completely resolved by action would indeed be resolved by the genocide of all non-rationalists that meet the aforementioned requirements.  Furthermore, rationalists would not have to deal with the infuriating stupidity of non-rationalists who ironically think they are not misaligned with logic.

On a purely pragmatic level, this could lead to the greatest circumstances of human flourishing possible.  There would be no philosophical pettiness, moral hypocrisy, or social obstacles to every individual's embracing of logical truths.  There would be no belief in fallacies if every adult looked to reason instead of emotion, comfort, societal attitudes, or any kind of assumption.  Any irrationalists who somehow escaped the purge would likely be in such fear for their lives that they would withhold revealing their pathetic worldviews or even try to outwardly imitate the rationalists they encounter.  As far as sheer pragmatism goes, it could not get any better for rationalists than this.

There is no evidence that killing non-rationalists is morally just, and the evidence in favor of Christianity means there is evidence that it is actually unjust to kill someone outside of self-defense, legitimate warfare, or execution for a handful of capital sins.  Even aside from this, it it would be irrational to think that non-rationalists deserve to be killed by default because of the non sequitur involved, as much as some of us might wish it were not the case.  In either case, not only is utilitarianism asinine, but killing irrationalists and anti-rationalists would objectively be the best way to bring about a world filled with people who understand and embrace the truths of reason.  It is just that utilitarianism is a logically invalid moral system.

Logic, people.  It is very fucking helpful.
