No way, I'm not buying into those statistics

I found this when poking around the web for more links to post on the Homeschooling Freedom blog. It's on the Homeschooling News and Muse blog. Scroll down to "If you repeat it often enough..." and then scoot over to Insight on the News.
Here's the quote,
"It's difficult to get exact numbers, but about 80 percent are evangelical Christians and 20 percent are nonreligious," said Ian Slatter, a spokesman for the Home School Legal Defense Association in Purcellville, Va."
So where does that leave me? I don't fall into either of those categories. A Catholic homeschooler definitely doesn't not fall into the evangelical Christian grouping and not the nonreligious either. There are all kinds of other religions homeschooling.
The article is from 2004.
So what's your take? Put in the comments if you think this was a misquote, HSLDA really believes that, or any other thoughts you have on the quote.
