"Fireworks: bad because I don't see the fun of them, and they scare/harm wildlife and pets, and litter everywhere"
"Pets: good, because I do see the fun of them, even though they scare/hurt people, scare/hurt wildlife and shit everywhere."
"Also, my poor dog/cat who I definitely got when garden-based fireworks were a thing, is terrified, but I take no responsibility for homing an animal slap bang in the middle of a world where these things exist, and everyone else should just stop."
For the record, I don't do fireworks, I do have a couple of cats who don't enjoy the firework experience, and will be getting a dog soon. But my preference isn't the point, my choices are my choices, and I have to take responsibility for them.
I don't expect the world to change to accommodate me, or judge others for liking things I don't, and who make choices that have no greater negative effect on the world than mine do.
Also, while cars are a necessity for many in a way that pets and fireworks aren't, they still kill/harm/scare/pollute more people, pets and wildlife than fireworks do, and not only because of entirely necessary journeys, and safe and considerate driving - I'm sure everyone who hates fireworks never drives when they don't need to, or just for fun and always take public transport when available.
