I've noticed I write a lot different because of combative online arguments. I have a problem.
So much of my communication is directed to people who don't want to hear me or understand me. So I've become very punchy and repetitive, trying to hammer home ideas that people are either unable or unwilling to understand.
I need to find ways to talk to people who want to hear and understand me.
It's hard to find other people who actually want to hear and understand though. People have different interests, and even when people appear to be working towards the same goal, they often aren't; like a boss who just won't understand the bad news, because it's easier to ignore the problem.
