Think about this number 5 for a moment. Using a simplistic statistical model it means that you have a ~0.4% risk of getting murdered by a gun over a 80 year lifetime. That's not far off of COVID as an unvaccinated individual. Now compare how people react about that news...
I'm aware of the difference, but it just means a different probability distribution. COVID's is likely very spikey, i.e. only there for a couple of years until you've successfully vaccinated, which we potentially already have, or until efficient treatment is found. Gun violence is there to stay with you throughout your life until society changes. Good luck.
We're doing something about COVID though. Even if some people are shouting "it's my right to have COVID", the vast majority of the population won't accept that stance. That's simply not the case with gun control.
