Good, we have the case studies -- now let's apply some critical thinking skills.
I've been applying critical thinking skills all along. I think it's pretty clear that you've made up your mind about what 'the truth' is (which is a flawed way of thinking in itself) a long time ago, and the basis for your belief is grounded in politics, not science. Let's back up and look at your response each of the four times I posted the same article.
I initially responded to you saying this:
The only research I found were laboratory simulated dummies exerting aerosol particles into a mask versus aerosol particles without a mask, which is something I or anyone else disputes. In some studies, they used real people, an example here -
https://www.nature.com/articles/s41598-020-72798-7What we dispute about masks is whether viral spread occurs because people enter a store, sneeze on everyone, and leaves -- and that a mask would somehow solve the issue, or whether the virus spreads through more complicated mechanisms that aren't well understood. And this isn't even taking into account the issue of people reusing masks, touching the mask which presumably has viral particles on it, then touching other people/surfaces, cheap masks that don't create proper seals with the face, ect.
Sure, in a laboratory setting, you can create a circumstance where droplets are captured in a mask, the real world isn't so neat and tidy.
I responded with a list of studies and articles, and you responded:
Your 10 seconds of google searching isn't a replacement for quality studies that account for real world factors, I had a feeling you knew that though. I clicked on the nature article you linked, because it's a credible journal, and they posted a study that was identical to what I said earlier, a laboratory setting where masks are used to measure the spread of aerosol particles in a controlled setting. Covid spread is not that simple, don't know how many times I need to say it. It was just two months ago when the CDC revised its social distancing guidelines from 6 feet to 3 feet. It was 4 months ago when they said it was 15 minutes in totality for high risk transmission, not just 15 minutes of sustained contact. We've been at this for over a year and we barely know anything. We don't know the exact mechanism of "super spreaders" either.
And I responded...
Cool, click on another one then, try this one?

Read the abstract, check out the table with all the different studies and results...and don't just bring up one study that you think is easiest to discredit and then use it to discredit all of them. Look at the results of all the studies as a whole. I'm not going to keep holding your hand and do all the research for you. It's obvious the evidence clearly points to masks being effective. We're still learning new stuff and we don't know precisely how effective, but that doesn't mean they aren't effective.
And then, without reading the article, you said:
I didn't say masks were not effective, I'm saying they are virtually useless in stopping asymptomatic spread in the general population.
This is an important point. You had clearly come to a conclusion, And it's now clear you didn't even bother reading the article (as I'm about to show).
In my response I linked the article again, and this time I copy pasted part of the abstract and explained that there were about a dozen studies included in the article.
And your reply included:
You're linking me to laboratory studies which refer to aerosol particle spread when people are "loud speaking", was one of the phrases your links used. Find me a single study that take into account real world factors of the issue of people reusing masks, touching the mask which has viral particles on it, then touching other people/surfaces, cheap masks that don't create proper seals with the face, etc. It doesn't exist.
These weren't laboratory studies. They were real world studies. If you read the article, I don't think you would have said what you did.
So then I literally took a screen shot of the table for you, from the article I posted 4 times for you, basically forcing you to look at it, and you come back with:
Good, we have the case studies -- now let's apply some critical thinking skills.
Now, instead of coming back with accusations of me taking things out of context since I didn't parse every word either of us wrote, how about you go read what the most qualified experts in the field think about masks and how they interpret the data. Don't look for the one off anti-masker with a phd, or pull a tvbcof act like you're more educated on the subject than they are. Forget all your preconceived notions about masks and just read what the scientists behind these studies with current leading rolls in their field think. Then you'll have applied critical thinking skills.
