When Will it End?

I was going to write a long essay.  Then I was going back to a poem.  And now... it's just what's coming out.
This writing is about the way we treat each other.  We're two-faced liars.  EVERYONE.  Even America, founded off of values of freedom and equality, is bitter.  Slavery, the way the whites treated the Native Americans...
And you know, Hitler got how to eliminate the Jews by how America pushed the Native Americans around, never keeping promises.
And the words we use to each other, MAN, we can be so AWFUL.  The n-word and the r-word (used for mentally handicapped kids) are NOT okay.  Ever.  It's always insulting people, always tormenting and being a jerk.  Words hurt.  A lot.  I don't know about other countries (or... other anything really), but I know for sure in my area it's really bad.
If we're going to continue to do this, how can we help anyone?  People are dying.  Every.  Single.  Day.  Why?  Because of something as pathetic as race!  There was a genocide because one type of Africans had lighter skin then the other type!  Not everyone's African, but we are all people.  Where has the respect for human life gone?
Having something as AWFUL as what's been happening AT LEAST in the last two hundred years shows a disrespect for life in general, I'd even go as far to say it's a disrespect to creation.  We're here, aren't we?  Shouldn't we be looking out for each other and helping each other?
Rather then killing people.
Rather then driving people to killing themselves.
Greed.  It's overwhelming.  But MAN, in my experience, all greed does it result in death and suffering.  For you Christians out there, Jesus preached of love.  "Love thy neighbor as thyself."  That's all it is.  And instead, we choose to hate our hearts out.
Hate, hate, hate.
We're all so full of hate.
It's time to change.  It's time to turn this around.
But I can't do anything but make sure I'm nice.  I can't tell you to be nice; I can't enforce it.  All I can do is stand (sit) here and rant my head off.
And now I'm just going to ask, keep asking what I've finally started asking, keep asking what I've finally learned, after two dang centuries of hatred and ignorance and probably a heck of a lot more then that.
When will it end?  When will it end?
When will we learn?
When will it end?
