How to shut up people who are against abortion

[Consilius]

First of all, God took no actions. He never takes any actions regarding how people behave. Instead, he simply saw it coming and punished the Egyptians when they did what they did.
Why WOULDN'T Pharaoh not want to let the Israelites go? They were kept under control and at the same time helped Egypt's economy by eliminating labor expenses.
Pharaoh put the nation's political and economic welfare above the human rights of the Israelites and was eventually punished for it.
"I will harden Pharaoh's heart" is the same thing as "I arranged that the person on the throne of Egypt during this time period will be one who disregards your rights and not want to set you free. But it's OK, because he will be punished for what he is doing and then other people will get the chance to refrain from doing the same."

When the Bible was written, everyone was a theist. That's why it needs interpretation. God knew what Pharaoh would do to the Israelites, but, at the same time, he KNEW it was going to happen, and at the time that he wanted. He didn't make Pharaoh hate Moses in the other sense.
Of course, the awestruck Jewish men who wrote the Torah gave God credit for their Exodus in a much more direct manner. To take that part literally, would, of course, contradict the Bible.

"I can't explain away a direct quote that interjects with a persons Free Will, so I'm gonna pretend it's not there and just act as if the person would act in that manner despite God's actions."

The Pharaoh had a hardened heart and God put him on the throne. So, we have:
God doing an action in "I will harden Pharaoh's heart" and we also have a Pharaoh with a hardened heart. God planned the Pharaoh being king, not him being a jerk.
