I'm in NY, and I'm very happy with the current set up of my not having to interact with people who have guns with them. I am in favor of keeping that arrangement, and I'll eagerly avoid going to places where that environment does not exist. The nice thing about America is the state model allows for something of a free market of ideas. People can collect themselves in places where they have similar mindsets to others and fashion a society that reflects their desires, interests, and needs at a local level. Some states can have permissive gun laws and I'd very much like others to have restrictive ones, and then everyone can happily go and do their thing accordingly, content to leave the people in places that do things differently alone. That last part is very much integral to the effective functioning of this system, and it's the one we need to work on most.
As for guns on golf courses, I can't imagine why anyone would feel so compelled unless there were dangerous wildlife around the course, in which case, I'd suggest the solution might involve addressing the underlying issue. Birdies belong on golf courses. Cougars, not so much, haha.
If you're in NYC you don't have to worry about people carrying guns but on Long Island it's not that difficult to get a concealed carry permit.
