Masks are for pussies!
Any real man and non-coward would've immediately gone and purposefully infected himself and his family, since there is no chance any healthy person possessing a healthy immune system will have anything more than mild symptoms, let alone need hospitalization, let alone die.


That's what our fellas here all did, amiright? Must be, because they're not cowards.

Anyone who says they don't believe the wearing of masks can help to reduce the spread of Covid-19 is either ignorant, lacking in common sense, an anti-science moron, or just a right wing asshole without a shred of human decency (much like Trump, their once and former president).


Scientific Brief: Community Use of Cloth Masks to Control the Spread of SARS-CoV-2 (Updated Nov. 20, 2020)

Source Control to Block Exhaled Virus

Multi-layer cloth masks block release of exhaled respiratory particles into the environment,3-6 along with the microorganisms these particles carry.7,8 Cloth masks not only effectively block most large droplets (i.e., 20-30 microns and larger)9 but they can also block the exhalation of fine droplets and particles (also often referred to as aerosols) smaller than 10 microns ;3,5 which increase in number with the volume of speech10-12 and specific types of phonation.13 Multi-layer cloth masks can both block up to 50-70% of these fine droplets and particles3,14 and limit the forward spread of those that are not captured.5,6,15,16 Upwards of 80% blockage has been achieved in human experiments that have measured blocking of all respiratory droplets,4 with cloth masks in some studies performing on par with surgical masks as barriers for source control.3,9,14

Filtration for Personal Protection

Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns. The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron .14,17-29 Some materials (e.g., polypropylene) may enhance filtering effectiveness by generating triboelectric charge (a form of static electricity) that enhances capture of charged particles18,30 while others (e.g., silk) may help repel moist droplets31 and reduce fabric wetting and thus maintain breathability and comfort.

Human Studies of Masking and SARS-CoV-2 Transmission

Seven studies have confirmed the benefit of universal masking in community level analyses: in a unified hospital system,38 a German city,39 a U.S. state,40 a panel of 15 U.S. states and Washington, D.C.,41,42 as well as both Canada43 and the U.S.44 nationally. Each analysis demonstrated that, following directives from organizational and political leadership for universal masking, new infections fell significantly. Two of these studies42,44 and an additional analysis of data from 200 countries that included the U.S.45 also demonstrated reductions in mortality. An economic analysis using U.S. data found that, given these effects, increasing universal masking by 15% could prevent the need for lockdowns and reduce associated losses of up to $1 trillion or about 5% of gross domestic product.42

Conclusions

Experimental and epidemiological data support community masking to reduce the spread of SARS-CoV-2. The prevention benefit of masking is derived from the combination of source control and personal protection for the mask wearer. The relationship between source control and personal protection is likely complementary and possibly synergistic14, so that individual benefit increases with increasing community mask use. Further research is needed to expand the evidence base for the protective effect of cloth masks and in particular to identify the combinations of materials that maximize both their blocking and filtering effectiveness, as well as fit, comfort, durability, and consumer appeal. Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation.

Who really cares?
They know the rules and presumably agreed to them.

I am sure the NFL has all kinds of other rediculous rules purely for the "optics".
Nice work on not addressing the issue pretty much at all regarding what is the valid safety argument that the NFL has taken those measures

If the indications that severity of illness correlates with infecting dose then masks would be very helpful. Just because they don't give you 100% protection doesn't necessarily mean they are not helping.

Its possible the NY outbreak was as bad as it was because people were not wearing masks and those getting infected were recieving much larger numbers of virus particles.

This alone would make masks more than worth wearing.

Just saying the same old dumb s__t, over and over and over.

"Country X required masks, and lots of people still died. Therefore, masks don't work."

No, dumb f__k, it means that if there had been no mask requirement, then more people would've gotten sick and more people would've died.

Any actual doctor promoting conspiracy theories about masks, should have their license to practice in the state of Minnesota taken away.

That should include online message boards.
