Homosexuality

Those definitions are straight from dictionary.com, go look for yourself. Rational =/= logical. And arguably a spree killer shooting up a school is in fact logical. Take Columbine for an example. The kids that went ramped there hated almost everyone at the school for numerous reasons, which is why they went and massacred them. They only went and killed those they had something against. Those who they had liked they let walk out unharmed. Who's the one using faulty arguments now?

Yet again, rational doesn't mean its right. Rational means it has a reason behind it. If you can find me a reliable source saying that rational = morally right, then even then your argument isn't very accurate since morals change from person to person. What one person thinks is right might be what others think is horribly wrong.

One last time, the definitions I gave are directly from dictionary.com so how are they false definitions?

The dictionary definitions aren't wrong, what you personally are applying the labels "rationality" and "logic" to are incorrect.
