My $3 mask is better than most masks worn in hospitals.  Of course, my wife is a doctor and she made our masks herself. 
Of course, the $3 doesn't include the cost of the $2,000 sewing machine.

But to be perfectly honest, I feel my stated position is based on logic and the best information available.  Personally, I'd just as soon nobody wears a mask.  That way either a whole lot of people will develop a more robust immune system, or they will die removing a bunch of weaklings from the gene pool.  It will probably also take out a lot of people that think they don't need to wear a mask because they are so tough.

So pardon the hell out of me if I don't care if you, and a whole bunch of other people die.  The world has too many people anyway.  My biggest regret is that might leave me in a world populated mostly with liberals.

Sometimes you’ve got to clear the deadwood so the forest doesn’t burn.

What I take away from this is that Vietnamese cloth masks are better than nothing, but Vietnamese medical masks are better than cloth masks.  That's what their data indicate.  What i don't know is what they mean by "cloth mask".  My cloth mask is three layers of T-shirt fabric sandwiching a coffee filter.  I suspect it is thicker and more effective than most surgical masks.

All that said, this study is actually fairly useless, as it tests the wrong thing.  I never said my mask would keep me safe from the virus, I doubt in the strongest possible terms that it will.  I do think it will attenuate the spread of virus should I become infected.  That is a separate question that they did not address in this study.

Did you miss the part about an INCREASED risk of infection by wearing a mask?

Key words being "managed and mitigated" risk.  We pay hundreds of dollars for "certified" parts that would cost $5 on the open market because the government tells us to.  Pilots take recurrent training because the government tells us to.  IFR pilots won't fly in IMC if they are not "current" per the FAA rules.  We don't drink and fly, we don't fly over gross, we make sure we have that stupid little compass correction card that nobody ever uses because the government mandates us to "be safe".

But people don't want to wear a $3 mask because they are not 100% guaranteed to keep them from catching a serious disease.  Perhaps as pilots, we should fly in IMC using only an Ipad because it is not guaranteed to kill us.

Your $3 mask can likely create a moisture spot in front of your nose and mouth that acts as a wick when you walk through an aerosol germ cloud, allowing you to breath in the germs when you’re well past the person who sneezed or cough.

So pardon the hell out of me if I don’t want to risk my own health so you feel more comfortable.

The problem is if you go out (and odds are you must, unless you're having essential delivered) you can spread the virus.  If you mask up the odds on your spreading the virus diminish.  Your behavior affects me when you infect me with your virus.  Hence it is reasonable for me to ask you to modify your behavior.

Actually it is not. There is have been plenty of articles, and a discussion with my veterinarian daughter, that cloth masks likely will harm you, by having the inevitable moisture spot in front of your mouth and nose serving as a wick, whereby any sneeze or cough through which you walk will be stuck to the cloth mask, allowing you to inhale those germ laden molecules long after you pass the person who made the germ cloud.

I will not risk my health so you can feel better.

I’m certain the NFL hasn’t calculated the permanent effect their actions will have on their league. When everyone is standing for the black national anthem, but everyone on the field takes a knee for the Star Spangled Banner, they will have jumped the shark with a large number of people. They will suffer a permanent loss of a large number of people.
