Christian Rap is a hard concept for many to get their arms around. But I think I would rather have my kid listening to that than the violent explicit lyric variety. And we are not to hide from the world - rather we are to rise above it and in so doing be the salt and the light for it. Rap in and of itself is just a type of poetry to music. If we can bring it out of the gutter and into the word it can be a tool rather than a detriment.
Salt and light, yes. But you are not acting like salt and light with “Christian” rap. You say the regular stuff is violent. How does Christian rap expose secular rap? How does Christian rap explicitly rebuke rap? Look at rap’s origins and the subject matter rap encompasses throughout its history. It is inherently violent. It is angry violent music, highly illicit sexual music.
And to say the music itself has no bearing is to deny the power of (ANY) music and the very heavy beat that comes with rap. And the way people dance to rap - well, they could just as easily dance lewd and sexually to “Christian” rap because there’s no difference in the music.
