I love that quote.
The real problem or mistake that is the cause of not only the abortion tragedy, but many other ills we see is this:
Mistaken identity. Being bereft of understanding the nature of the soul, people identify only with the temporary shell - vehicle - body. They think life is an accidental, meaningless occurance, isolated in a vast accidental purposeless universe, that life is a chemical by product, with no meaining, purpose, no God in control. No one is the witness of their actions, no one hears prayers or sees their hearts, there are no reactions to anything they do. Heaven and hell are antiquated theories (fairy stories), "as you sow, so shall you reap" - the immutable law of karma - is fiction to most people. Therefore, in the few years a person thinks they will be alive, not seeing eternity stretching before them, they see immediate personal gratification and sensual and mental pleasure as the only goal in life.
Therefore, why not break all the old rules, if they are not based on Darwin's law of the fittest? Grab pleasure when you can, and if someone - a tiny unborn someone - gets in the way of enjoyment, there's no harm in getting rid of the obstacle. After all, humans - and animals - are just machines made of meat.
I don't see any hope unless people have spiritual renewal, individually and enough enough indidviduals that society is affected.
And I am not seeing this in a sectarian manner; some of you have read my posts on Vedic understanding of God.
As long as people are ignorant of the reality that the real self is an eternally existing soul, (jivatma in Sanskrit), and that we all have an eternal forgotten relationship of kinship and loving service with the Supreme Lord, not only will such evils as abortion and sodomy continue, I believe they will get worse, as they have been doing.
