I believe everyone has a right to do as they please in their personal life so long as it is within the law and harms no one. As such, I cannot agree to the banning of fireworks. It is up to the individual to take proper precautions to avoid their triggers and, if impossible, to work with a therapist so they can manage their negative emotions. Hell, my obsession over contamination and the human mouth are triggered every single day, but I'm not going to demand everyone start wearing flu-masks.
I'm sure you are working on it and that this was more of a joke than a serious suggestion.
