Are people saying anything at all encouraging when they say they are human?
Humans do so many horrible and disgusting things. They speak absolutely incredible obscenities. Are they not all human? Is what they do human?
How can humanity hold itself up as a shining example of life, morality, decency, and have so many who are among the worst examples of life possible?
Is it really a good thing to promote that people behave more human?
History would reveal that humanity is vicious, murderous, ignorant, and vile. Nothing has changed, it is still vicious, murderous, ignorant, and vile.
Change may be impossible. These base qualities may be inherent. Even the human intellect seems incapable of over-riding these base desires.
Extinction may be the only course available for humanity.
