I don’t know what you want from other people. You’re not obligated to argue with people on the internet, but you started a disagreement that you weren’t willing to back up. Then you baseslessly called everyone idiots and a danger to the left before storming off. Maybe when you have more distance you can learn some lessons. Maybe you can understand where they’re coming from. Maybe you can better articulate what they did to harm the discourse. At the very least, it would be wise to learn to not pick fights you don’t want to actually participate in, for your sake and everyone else’s.
