I disagree. And I do so as a Wiccan who has raised her kids Wiccan. Teaching the fact of religions in a comparative religion class is one thing, in high school as age-appropriate. Teaching religious doctrine is another. Home, or the places of worship are for teaching a religion. If I don't want my kids (or grandkids at this point, rather) to be taught Christian mythology, then I need to agree that someone else's kids shouldn't be taught Wiccan mythology.
