It was only a matter of time before endless terrorist attacks by Islamic extremists produced a backlash from the extreme right. But the hate is not confined to these two groups. A vicious rally by the extreme left in London recently showed masked thugs assaulting a protester who simply held a sign saying he believed in free speech. These are the same extremists who dress in black and trash stores in opposition to globalisation. 
Every sector of society has its extremists. It is up to us all to speak out when we see hate, whether it is from the extreme right or the extreme left, whether it is the promotion of hatred in a mosque or any place of worship. 
More and more people are being dragged into this circle of violence. The only thing necessary for evil to triumph is for good men (and women) to do nothing.
