I have only one rule: don't be a dick. Allow me to clarify. You'll know you're engaging in dickish behavior if that behavior includes:

Basically, if you attack someone, for pretty much any reason, I'll feed you to the dragons. If you're only here to pitch your product or project, I'll apologize before feeding you to the dragons because I know it's tough and everyone just wants to try to get ahead. This is my castle. My rules.

“Congress shall make no law…”

I am not the United States government. The First Amendment does not come into play here. Like, at all. If you only remember one thing about freedom of speech, please let it be this: freedom of speech does not mean freedom from consequences. If you remember two things, remember this: freedom of speech guarantees the ability to speak, it does not guarantee a platform. You want to be a dick, do it somewhere else.

If it's just a misunderstanding, if you didn't mean what you wrote, I'm sure I'll—I'm just kidding. Nobody is accidentally a racist. You post something vile, you're out.

Play nice.
