Symbolism in television Programs such as True Blood

True Blood is a television show that uses mythical characters as symbols for both past and present events. One of these that stands out to me is when the Vampires are given the right to marry, this would be a symbol of Homosexuals being given the right to marry one another. Another one is that the Vampire's curfew has been lifted and in many countries (such as Australia) the indigenous had to fight to get the same curfew as everyone else. In one episode you see a burning cross and the in the opening credits you see a boy with what looks like a KKK costume on which as both strong representation of the KKK.The thing that has made people tune into the show week after week is the mythical creatures and the story lines that are being used to demonstrate these symbols.
