I genuinely think the only way to stay sane and productive on the internet is to ignore the overwhelming majority of people. Of course, you immediately create an echo-chamber for yourself, which can be dangerous. But the alternative involves constantly dealing with trolls, idiots, and people who you have fundamental, and irreconcilable, ideological disagreements with. Better to stay in your bubble, only to occasionally poke your head out so as to orient yourself and check your biases.
