There was a time in my life when I really enjoyed fireworks. Then when I was 10, I got a dog. After seeing how much dogs are afraid of them, it turned me sour on the whole thing.
Then later in life, I met a lot of war veterans with PTSD, and it's really, really tough for them too. And that made me really hate them.
So now, I feel that if you light fireworks, you're a douchebag, and there are no exceptions.
