It would actually help if you had a conversation, and didn’t start off so negative. You can disagree, but that doesn’t make you right, so you shouldn’t go into a conversation thinking so. Even if you are right, say you disagree, state your points, and go from there. It’s just not a conversation with you most of the time, because you’re just interjecting how people are wrong. No one wants to hear that every time you join in.
There is always the option to not join in just to be negative, and put people in their place. Sometimes, it’s okay to just let people talk about outlandish things that will never happen. I’m just trying to help. If you come into the conversation like you’re willing to discuss things, people would be less apt to call you a troll, or take anything you say seriously.
