This "fact" is making a terrible assumption. Homeschoolers are better educated on average than the public school products, this I will not disagree with. However, a parent who has the time and resources to teach their children will almost always surpass the quality of education provided by the state. Let me restate your theory in a few different ways: The fact remains that 90% of homeschoolers are smarter than the Christians churned out by public schools. The fact remains that 90% of homeschoolers are Christians and they are smarter than the Christians churned out by public schools. The fact remains that 90% of homeschoolers are Christians and they are smarter than the average student churned out by public schools. This whole thing is a function of homeschooling and available parents, not religion. You are making the absurd hypothesis that Christianity makes people inherently more intelligent.
