We're not only telling you you're wrong, we're explaining why you're wrong, which is what debate is about. We are enlightening you, we're telling you how you could further your knowledge on the subject matter.
If you're unable or unwilling to understand the concepts we're dealing with then you have no one to blame but yourself. Again, perhaps a board that isn't focused on what you consider to be "a waste of time" would be more suitable for you.
And don't start with the OH HE DISAGREES WITH ME HE MUST BE TROLL AND SEXIST, there are more suitable boards for that as well.
