I edited the comment before noticing you replied:
Might? Is might a good scientific position to base something on? Might what? What's the criteria that it "might" reduce those transmissions? Size of the particle? Is coronavirus large enough for that to be the case?
Goodness you didn't right it, ok, I didn't suspect you did. They say "might", and that seem to carry a lot of weight in your response.
It wasn't the word might that carried weight with me, it was the fact you omitted that part in your quote. I find for the sake of transparency, if you are going to take a quote from an article that supports your narrative then by not quoting the part which undermines that point, no matter how slightly, is telling in itself.
Yeah, it "might" do something. Why would they say that, without backing it up with any explanation? Is that an agenda of their own?
What about their own conclusion:
Does that matter? Why not talk about that conclusion? "Looking at other studies, the conclusion is there is no significant reduction with masks, but hey, ya never know, it 'might' actually do something anyways..." LOL. Yeah, that holds a lot of weight ;)
