Rational.. irrational.. I hope you can see that it's a pointless argument. The word "rational" is highly subjective so we shouldn't pretend there's some objective measure of rationality.

* Kill an innocent civilian * Have or perform an abortion * Eat meat * Fight in a war * Drop an atomic bomb on a city * Commit suicide

That's all shit that some people call rational and others call irrational. The truth is that "rational" is a word we choose because it sounds objective and authoritative, but it really means: "something that makes sense to me"
