Half of these assholes promote crime and treating woman like shit. Lock them all up.
Sort of need evidence to lock people up. I'm assuming 'they' are the rappers, of course. Even hate speech is protected to an extent in the US, let alone something that's simply music with perhaps violent tendencies . We'd certainly not try to ban Stanly Kubrick's work in 'A Clockwork Orange', for his, positive from the perspective of the character, depiction of assault and rape.
Also, even if half of "those assholes" promoted crime, and misogyny, that's still half that didn't and should be free.
