I think one strategy is to engage immigrant citizens from countries that ban civilian gun ownership that are currently NDP voters. Remind them that here in Canada they have the freedom to own guns of various descriptions. They can get involved in target shooting and training to protect their families unlike where they came from or even escaped from. While I believe these Canadians are firm in their views regarding social programs, their minds may be open to the concept of personal freedoms gained as Canadians regarding self defence, personal hobbies and privacy, and even their new rights to hunt to feed their families.
This can be as easy as starting with a poster program in their communities showing immigrants from around the world in hunting scenes. Or others at shooting ranges practicing or in instructional roles in our firearms community. I believe exposure may spark enough interest to have these voters sway their leaders on gun control. There’s no bigger community of inclusiveness than the Firearms Community! Positivity can prevail.
