All I can say is that is the biggest pile of antiscience apologist BS I've seen today, and the worst part is it is a wolf's approach: wrapping itself in the sheep's cloak of innocent plausibility. "This" is not "how science works."
"This" wasn't some innocent middle school kid or uneducated disadvantaged person asking out of complete ignorance of biology.
He claims to be a RN. You are a RN (so you claim). You've taken Microbiology, or at least Biology. You and he have NO credibility to feign ignorance about whether a virus causes this disease. If you are really this ignorant, you should go back to school: Not nursing school. Biology 101.
He is pretending to be asking an innocent question "for science." What he really wants to do is turn a discussion, including one about COVID, into a discussion about cell phones.
He is a troll and you are being manipulated... or you are a troll too.
If you were genuine and thought him sincere, you would have explained that COVID-19 is not caused by a virus.
You didn't. You used the opportunity to talk more about cell phones.
Stop taking this thread off the rails.
