Believing that you're better than someone else for whatever reason does not help your opinion, or your intelligence for that matter.
Disagree with people all you want, but when the condescending attitude comes in, what makes you think people will want to hear you brag (obviously or not) about how they'll never understand your argument because you're so smart, or how you might say 'oh you keep thinking that if it helps you sleep at night, but I KNOW it's like this.' People who do that seriously need to be slapped.
If you really were smart, you'd be able to actually outwit someone instead of resorting to trolling techniques.
And if you're reading this and thinking, "What do I care if people don't like what I say?" Well guess what: you have to live with people in this world, and if you want anyone to take you seriously, you're going to have to learn to at least address other viewpoints in a civil manner. If you don't know how or don't want to, I suppose you're a moron who's just giving in to their emotions and has no sound, calm logic. Oh, what's that, you don't like me saying that? Then cut the crap yourself.
The sad thing is, is that I see a great deal of older teens and young adults doing this.
