Sperm has yet to impregnate the egg and can be discarded, as nature intended. There's nothing wrong with discarding semen and it's nowhere comparable to a growing unborn baby regardless of what you claim.
@tabzer - It looks like calling the baby in the mothers womb by other names than a baby and classifying it as a non-human helps these satanic baby killing lunatics deal with the fact they've killed and want to kill human babies. They are pure evil and calling the baby comparable to "cancer", which
@Lacius is doing is just wrong on many, many levels.
