  That totally strains the credibility of your "recent academic research"!
  
  
  
  
  
  
  I hope we can agree on the following:
  Right-wing terror exists.
  Left-wing terror exists.
  Islamic terror exists.
  Organised groups carry out attacks with logistical support and widespread applause.
  Loners carry out attacks with no support and no applause and no allies.
  Mentally ill people carry out attacks that look like terror.
  
  And I hope we can agree:
  It is wrong to blame right-wing peaceful democrats for right-wing terror.
  It is wrong to blame left-wing peaceful democrats for left-wing terror.
  It is wrong to blame peaceful anti-extremist Muslims for Islamic terror.
