mckinley: "The civil war was about economics and not the immorality of slavery"

It wasn't one or the other, it was both. If slavery was not immoral, there would have been no civil war. If the souths economy was not so closely tied to slavery, there would have been little objection to obolishing slavery. It was more economical (convenient) to use slaves, if you were able to overcome or simply ignore any moral objection to enslaving people and forcing them to work.

The same kind of ideological debate is going on today in regard to abortion. It's more convenient and economically more feasible to not have a child than it is to have one. Kids are expensive and time consuming. If someone wants to fool around but not deal with needy little people (who will drain his/her finances and freedom) then they too need to either ignore objections to or to justify ending the little gubers life.

Seeing the baby makes it much more difficult for overcoming the moral objections to killing it, that's why the pro abortion crowd objects to right to life groups encouraging mothers to get sonograms.

Pro abortionists will also tell you that you can't compare abortion to slavery, because one hasn't anything to do with the other. If this is true, then why was it necessary to make blacks out to seem less than human and the fetus not at all human? The only way to overcome moral objections to killing people is to make them out to not be people. This was true with slavery then, and is true today with abortion.
