Carnage

You want me to hold back?
   Are you kidding me?

You seem to be dropping half the facts,
  and it was the same when I was young.

Now,
   after a few years,
      I see it is just the same.

History is only a different story,
  and so easily confused.

Each rendition changes,
  and only those who pay attention seem to notice.

When did the teachers become the modern day story tellers?
