How about, " Do not violate others' rights and freedoms " ,. as a Golden Rule.
I worked in a group home for the mentally/physically disabled for about 12 years, and every year we had to attend various training. The place had high employee turnover, and every year basic questions were asked, one being "We never violate a clients ____". And all the newbies(which were most of them) would shot out "rights!" and the boss would shout "No! We violate their rights all the time! Try again!" And that always stumped them. The answer was "dignity". I thought a lot about that.
It was true. We had to. Sure, it might have been Joe Blow's
right to go out in freezing weather without socks on, but we couldn't allow him to do that. It was all in how it was handled. We couldn't say "Yo, dummy, get in here and put some socks on! You know better than this!" We had to handle it patiently, first by getting him inside, and then by explaining why this needed to be done. Even if it was something we'd just talked about two days ago...
I think this idea can help in dealing with people in general. Sometimes we have to violate rights, freedoms, and even preferences(or at the very least, strongly caution a person against doing as they please in a certain situation). But when it has to happen, its best done with compassion, rather than with an attitude of superiority.
