Depression lyrics

On tele, police are murdered, demonstrators are just killed
Why two different words for the blood that's spilled?
In this struggle, you decide who's right
But are condemned 'till the end of time, that man will fight
Condemned for all time are the super master race
They'll fight over religion or the colour of your face
When's the next Hitler? When's the next war?
When's the next time they'll exterminate the poor?
Who are they, who are us?
Is 90% of the human brain full of hateful pus?
