I've been posting on other internet forums for almost two decades now, and once in a while you get into a bit of a tiff, but honestly it's just like entertainment, no biggie. But just today, I'm posting on one of these forums, and a racist American Trump supporting xenophobe just riled me up. And it's still bothering me so much that I'm having trouble thinking about it doing other stuff.
Argh. It's never happened like this before. Minor issue, but it's really doing my head in.
