The refusal by Conservative MPs to agree to an anti-Islamophobia motion and their mockery of an Edmonton Liberal MP for having once worked as a bus driver are both additional evidence their once-great national party, like its Republican counterpart in the United States, is increasingly controlled by an extremist, offensive fringe.

Not that additional proof was really needed. The blowhards and bigots crowding the Conservative Party of Canada's interminable leadership race should be evidence enough.
