I don't mean to be harsh, and you may mean well with your Facebook page, but I have to say that your description paragraph is very weak. It does not make gun owners look responsible or mature. It does not make a coherent case for gun ownership. I recommend you take it down, and redo it. Right now you are harming, not helping, gun ownership in Canada.
A sensible paragraph would not sound like street trash talk. Do you think a non-gun owner reading that paragraph will have confidence that giving the right to own or carry a gun is a good idea?
A sensible paragraph would mention the fact that 2 million Canadians have a license to own guns. It would mention that shooting sports and hunting are a multi billion dollar industry that employs many thousands of Canadians.
A sensible paragraph would mention that far more Canadians die in swimming pools or snowmobile accidents than law abiding citizens die from guns.
A sensible paragraph would mention that shooting sports are enjoyed by many thousands of Canadians, and have been part of the Olympics from the very first modern olympiad, before most of the sports we see today became Olympic sports, and Canada can stand proudly with a number of medals in these sports.
A sensible paragraph would mention that taking away a right to self defense is a denial of natural human rights.
A sensible paragraph would close with something like: "When guns are outlawed, only outlaws will have guns".
There are many other things a introduction paragraph promoting gun ownership in Canada could say. But not what you have said.
Read some CSSA literature. Read some 2nd amendment literature. And put up a useful page.
Peace.
