Mankind deserves sacrifice - but not of mankind.

The proper study of mankind is man in his relation to his deity.

Brutality to an animal is cruelty to mankind - it is only the difference in the victim.

We need to teach the next generation of children from day one that they are responsible for their lives. Mankind's greatest gift, also its greatest curse, is that we have free choice. We can make our choices built from love or from fear.
