If your plan sounds like it would make a good video game and/or be illegal during sane times then just keep it to yourself.
If a person reads your reply and thinks someone must have just shot your dog, rewrite it.
If your post insults a particular race, religion, political ideology, nationality, or body-type act like a mature adult when it gets nuked.
Basically, treat everyone like they may someday decide whether or not to rescue you. Actually, that goes for real life not just here on ETS.
