The FAQ of all main sites and Meta Stack Overflow have a section which states:
Civility is required at all times; rudeness will not be tolerated.
Be nice. Treat others with the same respect you’d want them to treat you. We’re all here to learn together. Be tolerant of others who may not know everything you know. Bring your sense of humor.
Why is this missing from the meta FAQs of all other sites?
Is there more leeway, when it comes to civility, being nice and being tolerant, on meta sites?
