If I gave you the choice tomorrow of being infected with this seasons flu or the coronavirus, which would you pick? Hopefully you're smart enough to understand the difference between a 0.1% mortality rate and a 2% mortality rate.
Leading people to believe the flu is more dangerous has slowed (and is still slowing) the response, reducing preparedness, increasing the spread, and as such will have a part to play in loss of life from this virus.
Alarmism and panic do far more harm in situations like this than the actual virus itself.

The CDC estimates the death rate of influenza is at most 0.65% (61k deaths and 9.3MM infected) and at least 0.026% (12k deaths and 45MM infections)

COVID19 is both more transmittable and has a fatality rate an order of magnitude larger.

Furthermore vaccination is available and there is some herd immunity for influenza. Proven antiviral therapies exist for the flu like Tamiflu or amantadine (depending on specific flu subtype). COVID 19 only has experimental options currently, with no vaccines yet available.
Considering that COVID 19 has a far longer incubation period than influenza, it also has a greater potential for spread. Spread potential to a greater proportion of the population (due to less herd immunity and longer incubation) would mean fewer severe cases would get the proper resources to be treated, which further increases the morbidity and mortality going forward. There is potential for the health system to be overwhelmed. All these factors make it a very serious disease - far more so than the flu.
