If everyone is as belligerent and stubborn as you seem to be right now, then you are right that it is a waste of time. In my experience, that is not the case, and I benefit from hearing others' perspectives even if they do not persuade me. Some advice: you aren't likely to persuade many by ignoring their viewpoints or dismissing their character by grouping "Them".
