Well, there was a day when some people owned slaves, and other people objected to that, saying it was wrong.
And the people who owned slaves said, "Well, you're entitled to your opinion, but it's none of YOUR BUSINESS because these slaves are MY PROPERTY."
And abortion is the same as that, and the same kind of people are involved, those who make it their business to do evil, and those who butt into other people's business to stop a wrong.
