We have systems for that. We can join the various 'teams' of people doing the punching and we can, as a group, demand that they change their practices - next convention the group votes on replacing ball punches with a hearty 'punchbuggy' to the shoulder. Several leaders run and make promises on how hearty to make that shoulder-punch, and we select someone for the next election between face, neck and shoulder. You don't get to complain about where the 3 parties are punching if you aren't in there telling them to change their target - otherwise you got party die-hards saying things like "we've always punched to the neck, and that's what Canadians want."
