I'm on a large pluralistic Jewish Discord server and there is a lot of monitoring and rules regarding pluralism to make sure things go smoothly. I'll copy paste some of the relevant sections, for potential inspiration.

Rule 0: Please remember that this is a social server.
As a general rule, the moderation team values the friendly vibe of the server more than freedom of speech.

This server is not primarily a place for debates. This server is not primarily a resource for answering questions. Some people here enjoy friendly debates or serious discussions or answering questions, but joining this server and immediately trying to debate or treating users here as a resource to interrogate might be regarded as unwelcome behavior. Hang out with us a bit first, get the vibe, then ask away with pleasure. This is a Jewish space. Non-jews are always welcome, but Jews are often prioritized.

Rule 1: Don't be a jerk.
Don’t troll or harass people for any reason. Don’t use personal attacks, insults, or ad hominems, even against people with whom you are not debating, or people who are not on this server.

No antisemitism or other forms of discrimination. This includes things but is not limited to: bigotry (based on race, gender, sexual orientation, etc.), anti-denominational language, sweeping generalizations, bringing up conversion or Jewish identity status.

Don't proselytize for other religions or lack thereof. Don't proselytize for your denomination or group over others.

No unsolicited lecturing when directed at another person. (Lecturing is permitted when solicited.) It quickly becomes annoying and patronizing and can easily spark conflict.

Rule 3: Some topics may only be discussed in certain channels.
There is a category called "Serious" that includes channels for news/politics, Israel, and health/wellness. Due to the heavier content these channels are more heavily policed, especially the first two. Content that belongs in these channels should not be posted elsewhere. In other channels, we're generally fairly relaxed if the content belongs elsewhere. Try to be extra sensitive and considerate in these channels.

A note on sensitivity:

This server has a pretty restrictive and complex strategy for avoiding conflict between the various groups here that warrants a separate, longer explanation.

Like the sub, our aim here is to create a space where all different sorts of Jews can get along, hang out together and hopefully learn something from each other. Unlike the sub however, this is a small intimate space where people mostly know each other personally, some people read every message, messages are synchronous and strangers coming in every day are pretty minimal - it's just a different platform.

As such, we try to avoid inflammatory and offensive sentiments a lot more and plenty of very important and legitimate conversations do not have a place here. It's a bit difficult to reduce this to clear rules and that could be unnecessarily restrictive, so it's a bit ‘we know it when we see it’ and we ask that you try to keep it in mind and actively try to think before you type. But here are some general concepts and guidelines:

Disagreement and Pluralism:
Try to respect people with different views to you and remember that their disagreement is not because they're lacking intelligence or information. They likely already know of that great argument or rebuttal and simply don't find it convincing. And they likely have good reasons for their views, even if you can't think of any.

Rather than saying you disagree with someone else, say what it is you believe about the subject.

Try to talk to people, not at people. Share mutually rather than lecturing.

We use denominations to distinguish, to say something is correct or incorrect within a given denomination. However, this is an imperfect tool—denominations are full of individuals and groups who differ and disagree.

Try to specify what denomination you're answering for and what denominations you're looking for answers from.

When tempted to correct, remember that just because someone has a different understanding of Judaism doesn't make them incorrect. Check tags of the people in the conversation before responding.

There's always more leeway to discuss one's own experiences even if not about one's own group, but try not to generalise beyond that. If something isn't for you, you can say that and explain why, but don't generalize to something negative about the group.

We don't want discussions here about whether users really belong to their claimed denomination.

Avoid trying to build a consensus or show that an opinion is ‘the mainstream’, or otherwise implicitly manoeuvring, implying that your perspective is the best or only valid one. A provocation need not be intentional to be effective.

Sensitive Topics:
If you find something about another group distasteful, or you know others do, just don't bring it up. You may have neutral intentions and even wording, but that doesn't mean it'll be received that way or that the discussion will remain that way.

When in doubt, ask or err on the side of caution. Remember no one owes you an explanation.

Exercise particular caution around topics that are not only controversial but also perennial, that people are tired of being confronted with and having to explain. Similarly, be cautious in discussions about topics that touch on the major distinctions between denominations or that are currently or generally the major talking points about them.

If there's a conversation you want to have on the server but shouldn't, consider whether there's an appropriate user you can DM about it instead. If there's not, consider whether that's a conversation you really need to have anyway.

“It's just a joke.” No, it's probably not, not for the butt of the joke. Try to be reasonably sure it'll be taken well by them before making such jokes.

Whitelist of groups one may mock: Nazis, tankies, and missionaries/Messianics. Anyone else, political or religious, however silly and obscure they seem to you, there's probably someone on the server with at least adjacent beliefs who may be upset by mockery. Yes, even that group you just thought of.
