We will need to work up a more formal set of rules but here is the quick list.
No personal attacks. Heated debate is just fine, but keep it civil.
No bigotry of any kind (Racism/Sexism/Homophobia/Transphobia/ect.)
Any misleading content (eg. fake news) may be taken down at the moderator's discretion. You may also be asked to mark misleading headlines, or vague satire as such just to be safe.
