The more I see about Ken Ham, the more I see richly robed priests who were smiling on Calvary one day long ago. And while homeschooling isn't that terrible as long as you're aiming for a decent education level for your children, we have a really poignant example of how "keeping your children's education holy" can become abuse*. Not to mention Ken's "scientific" explanations of "well, God does that to show us how awesome he is, now shut up and keep reading these apologetics so you can stay out of Hell!"
Sylvana, I believe that Ken is convinced he's trying to "save" people but he's also enslaved by being law-bound, which makes him just as bad as the priests Jesus was opposing, and for the same reasons. Dogmatic, self-interested and self-absorbed people who are more interested in their personal influence or padding their "get out of Hell free" buffer than honestly helping anyone.
