Jenny McCarthy is busting all kinds of stereotypes and proving big-breasted bleach blondes are smarter than stodgy old dorks with degrees. The funny former Playboy pin up has been singled out for her autism activism and has just published a book on the subject, Louder Than Words: A Mother’s Journey in Healing Autism. She has been standing up for her son, Evan, who suffers from the brain development disorder. McCarthy tells the compelling story of watching her son literally die as he went into cardiac arrest from a vaccination that she claims later caused his autism. She spoke out about her experience on Larry King Live this week, including how a shift in diet has helped her son manage his symptoms. If you thought McCarthy was brave for posing nude, you should see her fight the health care establishment!
