Weve been asking the FluBros those very same type questions, for weeks.
They never seem to have any sensible answers.
Ignorance is bliss, until someone they know has this.
I will say that many of the original deniers have now come around.
I doubt that would make much difference as the attitude even then appears to be “people die every day” and they blow it off.
I admit initially I wondered if the threat was as serious until watching it spread like wild fire thru China, but even then believed it might be mostly contained there. When Trump closed our order to China all I could think of were the thousands of Chinese people already here who had been traveling back and forth for decades. THAT was my wake up call it was already here and when I began watching closely.
