In spaces that were explicitly created with the intent of hosting civil, respectful discourse, it is always appropriate to insist the that discourse remain civil and respectful.

Part of civility and respect is not demanding that other people see things your way, or supposing that there is something wrong with them if the evidence available to them has not led them to the same conclusion as you. Another part is not ironically laughing because things don't go your way. Another part is not insisting that you are being persecuted for entirely innocent conduct in a way that ignores previously provided explanations for why that conduct was not considered innocent by others.
