I personally know of people who voted Conservative, and are Anti-gun. They are in line with Con. fiscal ideals, but not on the gun issue. Just like every Lib. supporter does not want to prohibit guns.
I'm related to a few anti-gun conservatives. I grew up without guns in the house and no hunters in the family. There's been many debates that end in "agree to disagree" but certainly no fanatical argument for either side.
