Another one is (non-compulsive) persuasion.
Note that compulsion requires you to have governmental (or quasi-governmental) power and exclusion ("fences") requires a certain degree of autonomy and, basically, property rights.
However the question as asked is too high-level. Moral systems' responses critically depend on how acceptable the other moral belief is. Minor things are usually tolerated and major things are subject to compulsion or exclusion (given sufficient power). For example the US government doesn't care about the Mormons' conversion of deceased (indifference) but does care about polygamy (compulsion).
Note that compulsion requires you to have governmental (or quasi-governmental) power and exclusion ("fences") requires a certain degree of autonomy and, basically, property rights.
Specialized vocabulary and language in general can work well as a fence without needing property rights. Our community is perceived to do this via using terms not used outside of LW.
The Esperanto community does this and Esperanto speakers are more likely to do favors for fellow Esperanto speakers than for other stangers.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
