Argument: Abortion forestalls potential societal contributions of a human
Joseph Sobran, political commentaator - "After tens of millions of [abortion] 'procedures', has America lost anything? Another Edison, perhaps? A Gershwin? A Babe Ruth? A Duke Ellington? … As it is, we will never know what abortion has cost us all."
If you knew a woman who was pregnant, who had 8 kids already, three who were deaf, two who were blind, one mentally retarded, and she had syphilis, and the father was a drunk, would you recommend that she have an abortion? (Answer yes.) You've just killed Beethoven.
A poor black family in the South is expecting a fifth child. This family, because of its skin color, already has difficulty receiving help and are already at the bare minimum poverty level. The outlook for their present children does not look bright. Abortion or Not? (Answer yes.) You've just killed Martin Luther King Jr.
The Sounds of Silence, 2004 - (I'd have a quote, except my parents aborted me)
Beethoven's mother was sick and his family was very poor. Beethoven might never have been born if abortion had been available.
