I see your point, and fair enough, but I can’t help but wonder how many people have a “sincere interest in these issues” in the sense that they want to do anything but stick to their guns and ignore the evidence.
I commend you for what you’re trying to do. I don’t have the patience. I just think of the Creationists as a cult that’s largely limited to the U.S. South and Midwest and try to ignore them.
Creationists are not a cult, nor are they limted to the Bible Belt.
They are people who willingly ignore evidence because they want to believe a particular conclusion. All of us are prone to do that, if not about creation, but perhaps regarding other matters.
However, minds can be changed. Many won’t, but some will. It’s tempting to simply shrug one’s shoulders and say, “People can believe whatever they want. No skin off my nose.”
But truth has its own agenda, which is to win out in the end. It’s a battle between facts and faith, and facts are harder to change. But faith is a pretty dang strong thing, too.
