I think violence is absolutely relevant. The way I see it, things are nowhere near as savage as it used to be back in the day. I'd say we're getting better, definitely not worse. Unfortunately, while many are growing and learning, others are hanging back. I think there are some serious issues with humanity which, until we fix, will probably always cause us to stumble over each other. Some that know, are too scared or lack power to do anything about it. Furthermore, humans are stubborn... some people just don't want to change, or fear it. I think we'll get there some day, but no time soon, not until those aforementioned things are completely dealt with.
