When Tammy Aaberg wears her purple T-shirt that says "End the Hate" today, she'll be thinking of her son Justin. He killed himself after he was bullied at school for being gay.  "We are losing too many kids. This has been kept silent for too long," says Aaberg,  She is joining hundreds of thousands of young people across the USA who will be wearing purple Wednesday to call attention to the deaths of six youths who committed suicide after they were bullied or harassed because they were gay or were thought to be gay.
