*These "emotionally retarted, socially crippled" people still mate, just with others like them... so bullying is actually empowering the creation of more kids just like the ones you like to bully, but with double the emotional retardation
*Just because these kids might fail in the playground doesn't mean they can't make a positive contribution to human society - surely you want intelligence etc in your gene pool
People don't bully you because there's something wrong with you... it's usually because they're envious of some quality/think something is funny (body features which you can't "fucking fix"). If kids truly think there's something wrong with you they're most likely to not speak to you at all.
The sooner you learn that every single fucking thing any human being has ever done and ever will do was a result of an instinctive unconsciousness that rules over each and every one of our actions the better. Not even the bullies themselves could tell you why they bully others, and even if you did explain to them what I just said, they'd completely reject the idea entirely. But that doesn't mean it's not true.
Concerning what you said about people bullying "intelligent people", back in the day (hunter/gatherer day, that is) intelligence was nothing without good skills in leadership and communication. Thus, unsupported intelligence appears worthless in the eyes of a modern day human (instinctively- we have not evolved to the current human controlled environment at all yet, that's why there are still wars and shit, because we're still driven by hunter gatherer causes) and thus the fact that someone may be very intelligent is easily eclipsed by a lack of people skills necessary for us, as a pack, to want to sustain them as a life form.
And, in terms of what the other guy said about "Tall Poppy Syndrome", I believe that also has very strong primitive roots. If someone is actually better than everyone, we need to confirm this. Thus, we put them under as much pressure as we can in order to test their true ability. If they are as strong as we want them to be, they grow with the pressure and "prove us wrong", eventually becoming a great "leader" figure, and are most likely destined to become very successful in the modern world as they would have been in our primitive yet genetically current past. However, if we are able to knock down the tall poppy as a group of bullies (lol), then they were never good enough to think they were better than anyone ever was in the first place.
Bullying is how we rank people, because we are still of effectively the same genetic makeup as when we were no different from animals. It will take so long for evoloution to catch up to the immense technological innovations we have made as a species, I actually don't think it will ever happen and as such we will never have a perfect society unless we engage in hyper evoloution through genetic modification and shit, but I doubt that will happen as long as we have religious people and whaterver
But anyway, I'm not a bully, I'm probably wrong about everything I have said but this is how I have concluded it works and it has fukin worked for me.
