Is the web populated with 12 yo boys?

Sometimes it seems the internet is full of ill-mannered 12 year old boys
     (or people with a 12 year old's mentality)
   spreading their own brand of ignorance and hate.

It's a shame and it makes you despair for the human race
  and wonder whether it is full of unsocial dullards, after all,
 in which case there surely is no future!

I hope not and I think it's sad that such disagreeable people
 seem to exist in such large numbers and have such a desire
to bring other people down to their low level.
