I can't think of a family member I have who is anti-gun. A few have differing opinions (some support licensing/registration, others think it's a right that shouldn't be restricted in any way like me), but almost all of them are at least passively pro-gun. A few of them own and carry, most have shot with me, and none of them freak out about guns. One finds humorous that I'm "scared enough" to carry (but I've never gotten more than rolled eyes as a result of those discussions), and another is "anti gun, but not for cops/military," and not very vocal (at least not with me) about it.
I have a grandmother who doesn't like guns, wanted them out of the house within minutes of my grandfather dying, but was never bothered by him owning them. In fact, once I went to lunch with her, and when she hugged me she felt my gun, but just laughed like it was no big deal and said "Oh I see you're carrying, but how are you, what's new in your life?" My other grandfather thinks guns are barbaric (after taking many lives in combat), but he supports the right of the law abiding to use guns, just as a last resort.
I think it helps that as a kid guns were never made out to be taboo or a big deal in my house; they were treated like the stove, which was dangerous if mis-used, but a tool with a purpose that we were educated on.
I've only ever gotten into one gun discussion that resulted in someone going berserk on me, and later I learned that his mother was the victim of an unsolved firearms homicide when he was a little kid. With most people, I've found that an honest discussion (and education about what the laws are and how criminals are) can turn even the most anti-person who is a thinking individual into someone who sees the truth. I'll usually just ask why they don't think people should have machine guns/ carry on college campuses/ not register their guns if they bring it up, then take it from there.
One person I met who I'll never forget...she was violently raped at gunpoint, and she would leave the rooms if guns were ever displayed after that. She'd frequnelty say that she didn't have a problem with guns, or people owning or carrying them, but seeing them brought up too much for her. It amazed me to see someone who could support others rights even when they raised such visceral fear in her.
I'm open about guns, just like I am about religion, politics, social issues, etc., and I'm always willing to discuss topics with people and agreeably disagree if we don't see eye to eye. So like everything else, I'll talk about "hot topics" (and often find my views refined or changed on issues that I find important), and the one time it got ugly I got up and left.
All of my friends are pro gun, many own and carry, but that's not because of a conscious effort on my part to shun anti-gun folks, it's just the way it worked out I guess.
Gun ownership isn't "...a civil right afforded to citizens by the US Bill of Rights."
Armed self defense is a natural right AFFIRMED by the Constitution.
