Would this be wrong?
I like talking to random people. I can spout a lot of info at them, if they are receptive.
If nothing else, some of these people need a little nudge.
I have been bringing up these issues to people I have met, but not by me approaching and saying things like this. I have been surprised at how many agree with me, even though most of them really don't have any facts. They just see that something ain't right.
Smiling, laughing, and in extreme cases, whistling are all good weapons. In warm weather, ostentatiously sniffing flowers, or eating ice cream cones are also good.
Logic via spoken language will work, but it's very slow for some. I trip on the folks who wear masks while walking unmasked dogs. I think posters of how dogs can spread covid (remember those articles?) would be funny.
