I completely agree with that statement. This is one of those areas where it helps to have a broad base of non-homeschoolers who are at least mildly supportive of the concept. We do not have the numbers to fight a really determined government effort on our own. (I will say that the government can have my hypothetical kids, like my guns, from my cold dead hands.)
People like Scotswife who are sympathetic to homeschooling even thoug they have a different bias, are one of our strongest resources. It's not good strategic sense to annoy people of good will just because they're not as fundamentalist as us.
