Do you have a source for "third leading cause of nonviolent death"? According to CDC, a 24yo female death has a 113 : 2416 = 4.7% chance of being caused by covid, and a 24yo male death has a 195 : 6756 = 2.9% chance of being caused by covid. Not trivial, but I wouldn't call something with < 5% prevalence 'leading cause'. More accurate: "for 15-24 year old covid is a minor cause of death".

https://data.cdc.gov/resource/3apk-4u4f.csv

https://www.cdc.gov/nchs/data/nvsr/nvsr70/nvsr70-09-508.pdf gives you leading causes of death for 2019 by age groups.

But the groups do not match perfectly so you have to recalculate some https://wonder.cdc.gov/ucd-icd10.html

Thanks for sharing. It comes across as a stretch to focus on 'nonviolent causes of death', when the first three causes of deaths in 2019 10-24 age group (page 11) dominate the charts with cumulative 73%, and the first 'nonviolent cause of death' is cancer, coming in a distant fourth at 5.4% of total deaths.

If it was not US, homicide would be somewhere below diabetes so I would say that it is not a stretch to ignore these causes. Beside, these are more or less environment and genetics determined. If you are black man in 20s in US, I feel really sorry for you but this is your reality. But the risk of COVID-19 death can be manipulated.
