While KB5252's answer is nigh perfect for a single sentence answer let's go a bit further.
Protection- As much as the MSM tries to dismiss this as a legit reason for personal ownership the use of private weapons for self defense FAR exceeds the amount most are aware of. You could spend a whole day going over examples cited from this one source. (personally I've got a 10mm Glock at arms reach every night)

Hunting- I hunt but fully understand those who are not comfortable with it. Just remember, every time you grab a burger or peruse the meat isle for that perfect steak to grill you're in the club, you just had somebody else paid to do the dirty work. If anything hunting makes me feel like I earned it more.
Other- I'm always amazed at how many people can get sucked into shooting by merely doing it. There's a guy I know, friend of a friend kinda thing, who has a pretty pronounced left lean to him and never had much positive to say about guns, handguns in particular. I don't know how but somebody got him on a range and the next time I saw him he couldn't stop smiling when telling me about it. God forbid he ever gets himself on a skeet range. Anyway, LOTS of folks who would never keep a loaded gun in the house (protection) or consider hunting absolutely love target/wing shooting.
