It is a case-by-case basis. If they are anti-gun, that could be an issue. If they are negative, then it comes down to respect for you and your hobbies. I love guns and my wife understands and respects that (although she is on the anti-gun side of things). My wife loves scrapbooking and I understand and respect thats. We don't allow our hobbies to cause financial or marital issues.
To my wife's great credit, she continues to support my gun hobby even after I was shot. Even when I take out young boys to the range events. As anti-gun as she comes across, she has never once asked me to stop or prevented me from passing this skill/love onto my boys. She even went out of her way to join me on a trip to the range.
