In this movie, Simon and his classmates were on a field trip and were coming home on the bus. The roads were slick and the bus ran off the road and landed in a creek. Simon being the littlest person, he climbed out the window and saved his classmates. He sacrificed his life to save his friends. Simon Birch proved to Peter Singer that people born with defects could do something productive with their lives.
Singer is all for animal life even sometimes over a human life.
I mainly disagree with the dangerous philosopher, Peter Singer because he has no real experience to back up his theories. When he finally can relate to his research, he goes against it and that is hypocritical.
