You're ignoring all the other affected groups I mentioned and honing in on a single one that is easiest for you to argue against. I think that's a sign that you're out of it lol.
I'll repeat it one more time since it's difficult for you to wrap your head around:
COVID won't be holding us back this much come 4th of July and 2022. You'll be completely free to go out to public displays or even head out into a secluded area and be as loud as you wish. You can handle skipping fireworks this (hopefully) one single time in your entire life. It's truly not a big deal for you to just continue the celebration in other ways.
Grow up, get some perspective, and work on your empathy. I believe in you. Have a great 2021.
