Do masks stop the spread of viruses?

I don't see a lot of masks these days--occasionally at the grocery store, and even a woman driving alone on a nice day wearing a mask this week. This evening we went to a visitation, and one woman was wearing a mask. Perhaps she had a cold and didn't want to expose anyone, but masks don't stop the spread, according to all the studies done. Perhaps the best study hasn't yet been designed, but it's zero, zilch, nada. Of course, I said that in 2020, but I was shut down or blocked. https://www.city-journal.org/article/approximately-zero Don't expect die/dei hard government supporters to change--I looked at some of their explanations for this study, and they go by feels rather than facts. We've already given them so much power, I doubt they will give it back.
