Professional firework displays are ok. If it's scheduled ahead of time and there's some choreography and art to it and it's contained to one area, that's cool. It's the people setting off mortars at all hours of the day in residential areas that I have a problem with.
And I don't really want to see limbs blown off, it's just that I've interacted with enough people who hear arguments against it, and still set a bunch of fires and blow up a bunch of explosives outside my damn house, that I have to assume malice on their part. Like, every house on this street has dogs. They've seen how their dogs react to fireworks. Why are they setting off pounds of dynamite?
