And yes she has said bat shit crazy things like this on what will happen if her same-sex marriage ban amendment fails to pass in 2004: “It isn’t that some gay will get some rights. It’s that everyone else in our state will lose rights. For instance, parents will lose the right to protect and direct the upbringing of their children. Because our K-12 public school system, of which ninety per cent of all youth are in the public school system, they will be required to learn that homosexuality is normal, equal and perhaps you should try it. And that will occur immediately, that all schools will begin teaching homosexuality.” -- Senator Michele Bachmann, appearing as guest on radio program “

“You have a teacher talking about his gayness. (The elementary school student) goes home then and says “Mom! What’s gayness? We had a teacher talking about this today.” The mother says “Well, that’s when a man likes other men, and they don’t like girls.” The boy’s eight. He’s thinking, “Hmm. I don’t like girls. I like boys. Maybe I’m gay.” And you think, “Oh, that’s, that’s way out there. The kid isn’t gonna think that.” Are you kidding? That happens all the time. You don’t think that this is intentional, the message that’s being given to these kids? That’s child abuse.” — Senator Michele Bachmann, speaking at EdWatch National Education Conference, November 6, 2004.
Yes, if gay marriage is allowed then schools will teach kids how to be gay.
