But which golden rule? Here are a few from among the major religions, there are many more.
There are two major types - do something good to others, and do not do something bad to others.
The first type, which is offered in this thread, is the doing something to others. This for many is offensive as it assumes that the "doer" knows what the recipient would find acceptable. This style fosters evangelism, charities, and other proactive intrusions, whether people want it or not. Many charities foster dependence on that source which long term is harmful. These seemingly altruistic actions often trigger - "the greatest harm can result from the best of intentions".
The other style which I favor is the "do no harm to others". It is passive, non-intrusive, and fosters individual freedoms.
