“an unborn child to be just disposable” Because there is no such thing as a unborn child. The foetus becomes a child when he/she born.

“The Pro-life crew” The anti-abortion crew. They are not in favour of life, they are against abortion.

“The pro-life argument is that life begins at conception.” Anti-abortion argument is not valid as spermatozoids and eggs are alive as well. If a baby is human when the cells start to separate, I don’t see why it can’t be even before, as they are all “unborn (potential) babies”.
