Insert standard argument about zillions of flies can't all be wrong WRT poo.
Also the argument doesn't depend on a specific "meat" or seller or sales figures. How about mystery meat products at the food store like "olive loaf bologna" not even sure what kind of animal that comes from...
The OP claimed that McDonalds burgers were "inedible". Observably, millions of people do eat them, therefore the OP is wrong.
That says nothing about the quality of the burgers, or whether eating them is a good idea, or anything else. It merely demonstrates that people do, in fact, find them edible.
"How about mystery meat products at the food store like "olive loaf bologna""
What about it? People obviously buy it and presumably eat it, or it wouldn't be in the store.
People don't buy 6 million units per day when something is "almost inedible".
