I don't even know you, I doubt most people hate you. You probably just made a few extremely stupid posts in quick succession, leading to people assuming you are a noob.
For example, making threads like this are annoying. Therefore, another noob may assume you are a noob and treat you as one. However, if you manage to make correct observations, and agree with what a lot of people say on a thread, then post, they may take you as a more experienced player.
