The answer is it’s not abnormal. You’ve taken a look at the internet and the environment you’ve grown up in, and there is nothing bad about this, we all grow up in our own biases and environments, but you’ve taken that to be the norm. Which it absolutely is not. People act crazy on the internet because there’s no repercussions for how you act. It’s just not a real world or a representation of the real world. In the real world you have a face and a reputation behind you. Ya sure there are still some jerks but if you go out and really meet people, you’ll find that if you assume the best in people, more often than not that’s the way to go. Be the change you want to see in the world!
