The world has always been that way. Social media and the Internet has just allowed people to spread their crap to a wider mass of people. In years gone by you'd get together with your friends at a bar and talk politics, religion, sports etc, and now you go to social media and spread it to a larger audience.

Look at the atrocities committed in the past. I would argue that the world is a much better place than it used to be. You're right though. All we can do is control ourselves. We are most likely not going to change anyone elses mind.

Thanks for the comment @ericvancewalton!
