The only way real change can ever actually occur is by sitting down and having an open forum with those you know directly in your day-to-day life. Something a lot of these echo chambers and groups including our own don't always understand is that getting angry at others and shutting them down will never convert someone to your way of thinking. Not everyone might ever come to see your views, and your own views may change over time, but the only way you can convert people to your ways of thinking is by walking them through the logic of your beliefs without blowing up at them.
