Being a religious parent who homeschools also does not equate to teaching creationism and not teaching evolution. Many religious people would not refuse to teach their children evolution, since many religions, such as Roman Catholics, do not see evolution as contrary to their beliefs.
That's part of my point. Evolution should be taught as what most of science theorizes. You should not delineate a part of science just because you do not believe it's theories.
That's why you don't see most religious homeschoolers changing their minds about the subject because they are able to really see the farce which is evolution as fact.
