Even more than just the effectiveness of the mask, but also the severity of the virus. This is something this is determined by age and health. So of course, a nursing home should absolutely require masks because the elderly are far more susceptible to the need of hospitalization or dying from contracting the virus. On the opposite end, however, children are known to handle the virus much better and are far less likely to transmit it, so requiring masks in a school is much less needed, and often times can be cruel when the children are very young or have special needs.
On average, though, and I'm struggling to find the exact number, but I believe it's estimated about 0.5% who contract Covid will die of it, which is a very tiny percentage overall. So, if somebody says "You know what? That's not that bad," and they are perfectly comfortable risking getting the virus by going to Disneyland, or to Home Depot, or Ralph's, and those around them feel the same way, I think that's the right of the individual, and likewise it's the right of the individual to go elsewhere.
I do have other things to get to so I don't want to spend all night going back and forth about a mask mandate that won't exist in an hour and a half, but at the end of the day I just think it's a personal decision and we, as a country, need to be more respectful to those who choose to wear and those who don't. Everybody has their reasons and each person has a story. You will not be damned to hell just because you took your mask off at the supermarket, and you won't be meeting St. Peter at those Pearly Gates just because you wore your mask alone in your car, or vice-versa. Unless you're out there, knowingly having the virus, not wearing a mask, and coughing on old people in nursing homes, I don't see any reason to label a family not wearing their mask at Disneyland, vaccinated or not, as evil.
