I would suggest it shows that the person has a fundamental lack of scientific understanding about risk factors and mitigating circumstances (like being alone, dispersed, outside where there is theoretically a lot of space and wind between you and the person next to you)
The reason I know people have zero understanding of risk – no one is wearing N95’s in these situations. An ear-loop (surgical) mask mostly protects other people from your droplets if you were already infected. So wearing a ear loop mask for your own protection is a false sense of security.
Not anti mask at all, Im all for them when logic says so, but wearing one for essentially no benefit (surgical mask, outside, alone) is misguided at best. If you are that scared of or susceptible to the virus, wear N95, N99, or P100. At least that makes sense and will protect you to a very high degree.
