we need to hurt each other

Why do we need to hurt each other for our beliefs? Why can't we set aside our differences and live in harmony? Is World Peace that hard to attain? Still I have a dream...and will keep dreaming.

Dream of Utopia
Seas on fire
Ashes of dreams
Where is utopia?
Where war’s nonexistent
Only freedom
No unholy alliances
Blood feuds doesn't crawl
Brotherhood of men
Colors unnoticed
Under the shed
Shed of unity
On the valleys
Valleys of equality.
