1) Do you think there's any merit to the notion that abortion is a destroyer of love and peace -- let alone the greatest?.
I feel that this notion has a lot of merit.
A human infant is one of the most vulnerable things in this world. An infant, simply for being, should inspire feelings of gratitude and safeguarding in a person more than any other thing.
Now imagine something that is even more vulnerable than an infant, so vulnerable that it cannot survive independent of the body of one of the two participants in its creation.
The forced ending of a person's life is the greatest violation of a human being's most basic rights to life and happiness.
War is not horrible because of the destruction to the landscape, architecture or economy. It is horrible because it takes lives away.
Murder is not horrible because it robs the market of another consumer or a nation of a citizen. It is horrible because it disregards a person's basic right to life and possible happiness. Another human being makes the decision to act outside of his/her natural abilities to give/sustain life and instead destroys it. It is against the nature of our bodies.
I would say that to destroy something so vulnerable for no reason other than convenience can potentially destroy a person's ability to love and may affect their peace of mind.
2) Is there any truth to Teresa's statement that abortion teaches people to use "any violence to get what they want"?
I would agree with this statement.
