But where is the 'proof' that it is life? What is your definition of life?
As an aside to where life begins and whether or not abortion is morally wrong, people who believe it is wrong and want it outlawed force the consequences of their own moral code upon others. I believe in choice. This does not force any of my own beliefs on others, if someone wants to have an abortion I believe that whatever their choice is, is the morally correct decision. So if they do it or not they are not wrong in my eyes. Nor does my belief system force consequences upon people who have a different set of beliefs to me. Which is the more compassionate way to behave? Force your beliefs on others or allow people to make their own decisions without judgement?
But those of us who don't agree with abortion would say you are forcing your choice onto a very vulnerable little life. That is genuinely what we believe, its not about making high handed judgments, its about feeling very sad and concerned that a little baby is having its life deliberately ended.
