Yup.
Don't tell salty this though.
She's probably never had to wear a mask for 12 effing hours.

But the reality is He does NOT present any solid hard scientific studies or evidence to back it up.
As I and other have pointed out the studies reviewed by many drs and reaserchers and
Report from the CEBM "The Centre for Evidence-Based Medicine"
Connected with the University of Oxford
Masking lack of evidence with politics
https://www.cebm.net/covid-19/maskin...with-politics/
their research looked at all the relevant studies done on mask and Found that there's NO honest way to claim that mask are effective.


....In 2010, at the end of the last influenza pandemic, there were six published randomised controlled trials with 4,147 participants focusing on the benefits of different types of masks. 2 Two were done in healthcare workers and four in family or student clusters. The face mask trials for influenza-like illness (ILI) reported poor compliance, rarely reported harms and revealed the pressing need for future trials.

Despite the clear requirement to carry out further large, pragmatic trials a decade later, only six had been published: five in healthcare workers and one in pilgrims. 3 This recent crop of trials added 9,112 participants to the total randomised denominator of 13,259 and showed that masks alone have no significant effect in interrupting the spread of ILI or influenza in the general population, nor in healthcare workers.

The design of these twelve trials differed: viral circulation was usually variable; none had been conducted during a pandemic. Outcomes were defined and reported in seven different ways, making comparison difficult. It is debatable whether any of these results could be applied to the transmission of SARs-CoV-2. Only one randomised trial (n=569) included cloth masks. This trial found ILI rates were 13 times higher in Vietnamese hospital workers allocated to cloth masks compared to medical/surgical masks, RR 13.25, (95%CI 1.74 to 100.97) and over three times higher when compared to no masks,* RR 3.49 (95%CI 1.00 to 12.17). 4

It would appear that despite two decades of pandemic preparedness, there is considerable uncertainty as to the value of wearing masks. For instance, high rates of infection with cloth masks could be due to harms caused by cloth masks, or benefits of medical masks. The numerous systematic reviews that have been recently published all include the same evidence base so unsurprisingly broadly reach the same conclusions. 2 However, recent reviews using lower quality evidence found masks to be effective. Whilst also recommending robust randomised trials to inform the evidence for these interventions. 5

Many countries have gone onto mandate masks for the public in various settings. Several others – Denmark, and Norway – generally do not. Norway’s Institute for Public Health reported that if masks did work then any difference in infection rates would be small when infection rates are low: assuming 20% asymptomatics and a risk reduction of 40% for wearing masks, 200 000 people would need to wear one to prevent one new infection per week. 6

What do scientists do in the face of uncertainty on the value of global interventions? Usually, they seek an answer with adequately designed and swiftly implemented clinical studies as has been partly achieved with pharmaceuticals. We consider it is unwise to infer causation based on regional geographical observations as several proponents of masks have done. Spikes in cases can easily refute correlations, compliance with masks and other measures is often variable, and confounders cannot be accounted for in such observational research. ....

MC, the guy in the PBS video you posted mentions at the end that "mask are NOT a political statement". I'd love to agree with that. But if they are NOT a political statement then they should NOT be mandated by political whims with bans, censorship, fines and threats of loss of Biz, and jail time.
So sadly the politics ARE in play and they in play for those who want gov't coerced mask wearing and against those who question the practice.

Tossing out the mantra "it savings lives" is still an assertion and an emotional plea.
But in this case it's not based in scientific evidence.


MC, BTW That was 13 minute video. I watched it all.
would you return the courtesy and curiosity and watch the 1st 13 minutes of the video below?
Oxford epidemiologists: suppression strategy is not viable
Prof Heneghan and his Centre for Evidence Based Medicine colleague Tom Jefferson who shared their thoughts in this wide-ranging discussion. ....
• Tom Jefferson: “Aside from people who are exposed on the frontlines, there is no evidence that masks make any difference, but what’s even more extraordinary is the uncertainty: we don’t know if these things make any difference…. We should have done randomised control trials in February, March and April but not anymore because viral circulation is low and we will need huge number of enrolees to show whether there was any difference”.
• Carl Heneghan: “By all means people can wear masks but they can’t say it’s an evidence-based decision… there is a real separation between an evidence-based decision and the opaque term that ‘we are being led by the science’, which isn’t the evidence"....

OSHA has set standards for the amount of CO2 concentration that should be in the work place. And what danger levels are.
In the video below (CENSORED from YOUTUBE BTW.. Because SCIENCE?) Someone checks the CO2 level under various mask. Most create levels of CO2 FAR beyond OSHA allowed levels.

Friday President Trump signed something into law amid the usual fanfare.

Photo op, 10 people present. All standing shoulder to shoulder not wearing masks. These were among the people signing the laws and having access to the billions of dollars of generated in corona data. Obviously they don't believe their own data, so why should I?

So outrageously funny is the title of this conspiracy theory article, I sent it to a friend to get a chuckle out of him. He was having a glum day and I thought I'd perk him up a bit.

Another Science denier. I've seen plenty of scientific journals and articles by actual scientists that state that simply wearing a piece of cloth over your nose and mouth does more harm than good, but have yet to see any study saying the opposite.

But you believe as you wish and continue to do as you wish, I will never attempt to stop you or ridicule you for your personal choices. But don't sit there and tell me that the science says anything different without any proof.
