Why are the Gaede Nazi twins permitted to make music with veiled threats in it, but rap is always censored?

The Gaede twins are two teen girls who sing and sell white power white hate/Neo-nazi music, to children and young adults. The producer from Resistance Records helps the teens advertise online and by going to school yards. Basically, a skinhead goes to different schools and pes out cd's to children and teens that are white. The cd's are intended to make young children into future Klan members, and encourage them to wish hatred and death upon non-white people. In the music, the songs are all about: "i hate black people" and "the world will be better if black people were not in it" and then there's some: "let's kill the black people so our environment will improve." The teens were on ABC for a doentary, and they were talked about, but in a positive way. Apparently "Aryan Man Awake" is not so offensive to the media as much as The Ying Yang twins are. Now, all we hear the media, and people complaining about is Rap music. Rap music is evil, rap is degrading and violent. Congress even had hearings on some rap singer's lyrical content. But white power music is never brought up to congress and you never hear anyone complaining about neo-nazi musicians and their violent lyrics do you? People act as though these bigots do not exist, as if they are not there. I believe this is done as a power strategy to help the white hate movement grow, but stay hidden in the shadows. It is said that the greatest trick the devil ever played, was making you believe he does not exist. If rap is going to be talked about like it's trash, than i think the garbage of neo-nazi pop and rock should be cleaned out too.
