This debate will never be settled. If you believe that life begins at conception, then you must believe abortion is murder. If you believe life only begins at birth or in the second trimester, then you can support abortion and believe it is not murder.
Both sides have very valid arguments, therefore no solution. If everyone was serious about reducing the number of abortions, everyone would concentrate on education and prevenention of unwanted pregnancies.
While I am personally against abortion, this is where I have a real problem with the pro-life lobby, as they hamper the two things that would most reduce abortions by not supporting better education and by not making contraceptives more readily available.
