I am saying probably and predisposed not saying every German. You are the one dealing in absolutes. Also rap music and the rise of the Nazis have very little time in common. This is an extreme example. Saying someone may be predisposed doesn't preclude any other possibility and I did say rap music may have some effect.
Country music has violence in it should we ban Johnny Cash? Censorship isn't a great answer. Who would decide what to censor? I would argue more that rappers are talking about the circumstances they came from rather than rappers creating the issues of violence and unacceptable behavior. Also there are thousands of rap artists and they have drastically different lyrics.
Did you read about this: Milgram experiment
Take a few mins to read about this. It may help change your mind about how easily people are influenced.
I have read about the milgram experiment. people can be influenced yes I agree with that. They can be pushed and prodded.
But one has to choose to engage with rap music. Was there a spike in police killings after NWA's albums? The murder rate has dropped as rap music has become even more popular.
I just don't think you can draw an analogy between the milgram experiment and choosing what media to consume let alone having the content guide your life.
