Chaos UK

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?
