Young actors often don't think of the consequences of doing nudity or sex scenes. They want the role so badly that they agree to be exploited and then end up embarrassing family friends and even strangers.
I rely on guns for protection in life. God does not say 'This is la-la land.' God doesn't say 'Welcome to Earth. Everything's perfect. There's no crime. There's no murder. There's no death.' The world is imperfect and you have to be on guard.
