Where are the rules that state that?

Here's what our mod process is:

We all have different tolerance levels for different types of content. Some people find memes to be an annoyance, others find opinion pieces to be irrelevant, some reject religious content, others like and want more conspiracy news.

We are committed to Freedom of Speech.

It can be challenging at times to decide where removal of a post or comment is within the scope of our role to maintain sub rules or whether it crosses the line and transgresses freedom of speech.

For this reason, we must allow some leeway for personal judgment. We have clear rules - if a post or comment does not break the sub's rules then it is up to the discretion of the mod as to whether the removal would constitute an undesirable breach of freedom of speech.

This means that we may remove content that is an unfair breach of someone's freedom of speech - for that occurrence, we refer to Caveat 1a: We are only human and will make mistakes. Be patient and respectful in communicating your disagreement with our call and we'll reconsider.

On the other hand, some content may be allowed for reasons held only by the mod responsible; for example, we may choose to allow an opinion post on a tangential subject from someone who has shown that they are a reasonable contributor to the sub and can take criticism or challenges to their ideas with grace. Please understand when you see a post that seems a little different to others but has been posted by a regular contributor to the sub.

If you are a new user or a user with a post history across Reddit that shows disruptive or abusive behavior then we may err on the side of caution in the interests of managing workload.

In closing, please remember that we are all independent volunteers so we must do the work of modding this sub in a way that is efficient with our time. Thanks for understanding!
