You're right, in general a lot of people pay lip service to higher principles when it's convenient, but as soon as the issue is something they don't like then there are all kinds of vague second-order reasons why the mere potential of another person's rights are harmful and must be restricted. Zoning laws and gun regulation are both great examples. But as another commenter pointed out I suspect that there's actually more overlap between these particular issues than otherwise, they're both hallmarks of well-off suburbanites who want protection from the rabble.
