First of all, not only are the majority of Canadians in favour of a ban on the type of weapons used in these sports, but the majority of firearm owners are in favour of banning assault-style guns. What's more, a number of surveys show that between half and two thirds of gun owners are also in favour of a ban on handguns.
Amongst firearm owners, only a minority use handguns or assault-style firearms for sport shooting. Amongst those, there is a minority that plays war or role-playing games in which they imitate police officers or simulate self-defence scenarios. It is that group that constitutes the firearms lobby. Actually, that is the firearms lobby. The IPSC is funded by the arms industry. It promotes handguns and assault-style weapons, and that's its bread and butter.
If you grant an exemption for this type of shooting sport, which is the polar opposite of what a legitimate Olympic sport is, the ban will mean nothing. Current handgun owners can keep their guns and continue to practise shooting sports. We just want to keep the situation from getting worse and keep shooting clubs from becoming places where this type of American-style sport is practised.
