I assume you're a moderator - although they're much appreciated by myself, these well-written tips will just get lost in the noise here. You might consider adding them to the FAQ yourself : )
For example, saying: "I can't believe you people are downmodding me." will most likely just cause people to pile on and punish you.
But saying: "To those downmodding me, if you think I meant this, I really meant that." or "Just to clarify, I meant it this way." will often defuse a misunderstanding and cause people to at least put you back up to 1.
Really the key is to be civil. It's rare that someone gets dogpiled just for dissenting. However, if you dissent in a rude manner, people are tempted to see how negative one comment can get.
