stupidity !rant warning!

You know those statistics that the news papers have sometimes? Where they tell you a few percentages of, say, number of children killed by bats every second(this did not actually happen), then you start thinking "hmm... bats really are dangerous". It makes sense, everyone can be scared by statistics and percentages. Also, think of this, at least 50% of all people on the internet are stupid, and I know you are now thinking "I don't see that much stupid on [insert favorite blog/web-forum here]", and it makes you wonder, "where does all the stupid go?", the answer: youtube.com comment boards. On web-forums, you can find the occasional stupid person/egotist/jerk, on the youtube.com comment boards, they are everywhere, the grammar and spelling are horrible and tend to look something like this.... well, actually, I probably shouldn't post a picture of it... just search for a popular youtube video and read the comments... you'll then understand. Now that you understand that, you have to remember, that is *JUST* the internet, there is at least twice as much stupidity in real life, we have idiots voting for our representatives. We must be doing something wrong. what happened to umm, I dunno, education?! Sure, our school system works for 50% or so, and everyone can do the important parts of math, but some people made this! AND SOME PEOPLE BUY IT! My thought is that if we want this world to move forward, we should start with better education. We have morons, we have idiots and, oh yeah! the occasional smart person! So if there is any life out on any other planet, and they have the technology to travel long distances through space, I really can't blame them for not making contact with humanity. Really, I have so much more that I could keep going on about for ever, and ever, but you've probably stopped reading at this point so...

TL;DR people are stupid, and there are only a few of us who have actually noticed this. Why do people have to be stupid?
