Clinical presentation of COVID-19 is radically different from Influenza. No actual doctor anywhere would confuse the two.
And producing similar symptoms doesn’t make the viruses any less different. The “common cold” is a set of symptoms produced by any of over 200 different viruses from multiple families. Four of those are from the coronavirus family. Most colds are caused by a virus in the rhinovirus family. Adenoviruses also cause a lot of colds. Totally different families of viruses each producing similar symptoms. The human body only has but so many tools to deal with infections, so there’s some overlap in what your immune response looks like.
“Clinical presentation of COVID-19 is radically different from Influenza...And producing similar symptoms doesn’t make the viruses any less different.”
You just demonstrated a classic (but low IQ) deceptive technique while contradicting yourself at the same time.
