There is no ad campaign more effective than good old fashioned parenting. Parents need to tell their children not to use words like "gay", "fag", "dike", "whore", etc. What child needs to use such words anyway???? For what purpose do they use such words, other than to humiliate and bully other children. Parents need to be on top of every aspect of their children's development. Teaching children to be nice should be a big part of their education.
