You can use facts and data as much as you want to, the "ordinary disease," "it's just a flu," "it's not dangerous" crowd will not believe you. The common response to the death number, as well as the almost universal conclusion that deaths are being undercounted, is that, in fact, the deaths are vastly overcounted. That every single death is counted as C19, hospitals are incentivized to classify every patient as C19, and you have to separate deaths WITH C19 from deaths BECAUSE OF C19. They'll cite you to a case of their friend, or cousin, or even themself, that didn't even TAKE a C19 test but received a C19 diagnosis in the mail.
See, the deniers take the position that the people dying would have died anyway because of old age, or cardiac issues, or pulmonary issues, and the inconvenient fact that they had C19 is immaterial, and just being used by the crazy media/elite conspiracy to destroy our country and institute complete government control over every aspect of our lives.
They scoff at your death numbers.
Meanwhile, the family and friends of those 169,000, or 210,000, or whatever the number is, are not scoffing.
