Rational is just knowing the best way to fix whatever problem your dealing with. If I'm hot, and I don't want to be hot, then I'll turn on the AC.
Ok.. if thats the case.. then there are some pretty scary scenarios that can result out of rationality.."The US needs oil. So why not invade the Middle East?" In that case, it seems "rational" but totally immoral. It seems rational to combat the problm of illegal immigration by deporting people.. but again, totally immoral.
Anyway.. I'm not going to let some sticky define whats rational or not to me just because its author has a PhD. I know when I'm being irrational but feelings and morality arent in the realm of rationality.
