Why is everyone generalizing hockey fans, people from Vancouver, etc. ?

FOR ALL U PPL OUT THERE AND I AM TIRED OF EXPLAINING THIS TO U DUMBASSES THE PPL WHO CAUSED THE TROUBLE YESTERDAY HAD NOTHING TO DO WITH 95% OF THE CANUCKS FANS. MOST OF THE DAMAGE WAS DONE BY ANARCHISTS WHO WERE THERE IN VANCOUVER LAST YEAR FOR THE OLYMPICS CAUSING THE SAME TROUBLE. THOSE ANARCHISTS HAD CAME PREPARED WITH GASOLINE AND ALL SORTS OF OTHER THINGS AND THE MIN THE FINAL WHISTLE BLEW THEY WOULD SHOW UP TO STREETS WHERE A LOT OF FANS WERE ON AND START CAUSING DAMAGE. SO STOP DISSING THE PPL IN VANCOUVER OR EVEN CANADA.
