Let’s be clear. There’s really no upside to fireworks.
They are momentarily pretty, sure, but there are so many things which are pretty. Stars, sun-kissed hills, ice cream, rainbows, art (misc). And most of them are pretty for far longer than fireworks.
And of the above, only one is an explosion, and stars are far enough away that I’m not immediately afraid for my life. Fireworks, on the other hand, are often very nearby, and are (in this country anyway) often handled by people who are wildly ill-equipped to manage explosives.
That’s really all I have to say.
Down with fireworks.
