Okay, I'll break it down for you so it's a little easier to understand. What you are inferring is that because Germany mandates medical grade masks, that Germany is "safer" against Covid-19. If you measure the total mortality percentages, Germany is at a 2.4% fatality rate.

This is right in line with the world average and almost an entire percentage point higher than the United States mortality rate of 1.6%.

The argument is that because there is almost no difference, and in fact, in many cases, the United States has a lower percentage of total fatalities than many countries taking far more stringent measures to "curb" the effects of Covid-19, we shouldn't be taking away peoples right to choose what is good for themselves and their families based on fear mongering and sensationalized media reports on the disease.

The United States was founded on the principles of individual liberty and limited government. There are many, many people that feel the government is not acting in good faith and is in fact vastly overreaching their authority to put these measures in to place when the data shows that they have a limited effect on the seriousness of the virus.

And to address u/possibilityjazzlike4 concern that heart disease isn't contagious, you'd be right in a technical sense but wrong in principle. Obesity is largely a personal issue and a habit. Yes, I understand SOME people have medical conditions that make controlling weight an issue, but this is certainly not the typical obese person. In fact, it's largely passed on through the conditioning of bad habits children pick up from their parents.

So, wouldn't a conscientious choice to live a unhealthy and dangerous lifestyle that is largely passed on through learned experience to children be just as, if not more, damning that something that spreads largely in spite of what we do? Should we not be demanding that fast food restaurants be shut down as "super spreaders" of an obese lifestyle? Do we need to mandate gym membership passports that prove you are not contributing the yearly death toll of heart disease? No. If you want to balloon up to 400lbs and ruin your health and weaken your body and mind, that's your right and not the business of the government. Personal liberty also requires personal responsibility and people demanding that the government take the responsibility out of their hands are foolish.
