I love dogs and have other pets, one of which is scared of fireworks.
However, the choices we all make for our own enjoyment and fun often impact others, but we continue regardless. This is often due to cultural norms, or because we're are unaware, or because some just don't care.
For example, there are lots of people who are terrified of dogs - children, people who experience severe anxiety due to a previous attack, people who have autism etc., should dogs therefore be banned? Thos people have to try and usually fail to avoid dogs 365 days a year, not just the 30 or so days a year when fireworks are likely.
Equally, I've known of cats who are terrified of dogs barking, should dogs be banned for that?
Fireworks can been seen as unnecessary; but aside from support or working dogs, then so are dogs - why is the right for people to own animals that can terrify people be seen as ok, but fireworks are morally reprehensible?
My point is that society is a homogenous group consisting of people with likes and activities that will sometimes conflict with the views and needs of others - at what point they became intolerable will be different for all of us, and it's up to the law and govt. to look at the evidence and make a collective decision.
I don't think that the evidence for banning fireworks is at such a point as to be justifiable, and certainly isn't evidence that couldn't be applied to other activities and choices that are considered socially acceptable - sometimes ones that people who want fireworks banned indulge in.
