 Other groups with similar aims, such as "Revolutions per minute" have also published papers which disparage fox hunting on the basis of the social class of its participants.Opinion polls in the United Kingdom have shown that the population is equally divided as to whether or not the views of hunt objectors are based primarily on class grounds.Some people have pointed to evidence of class bias in the voting patterns in the House of Commons during the voting on the hunting bill between 2000 and 2001, with traditionally working-class Labour members voting the legislation through against the votes of normally middle- and upper-class Conservative members.
