I haven't lost any faith in humanity, and likely never will. Have you ever considered that all the things wrong with the world aren't things to be hated/ignored/condemned/etc.? It's our imperfections that allow us as a species to learn and grow. Sure, it's sad that people support a guy like Trump, for example, but decades from now people will look back on the valuable lessons we've learned from the mistakes we make today. It's not a quick process; it will take centuries for us to really see the results of our civilization's growth. But someday, people will see how it was all worth it.
