COVID-19 and masks

Can we agree that the COVID-19 virus is spread through the air by those infected, by people like you and me, who exhale the virus with every breath we take?  If you think not, read no further.  I can’t convince you of this scientific fact. The breath from virus-infected persons contains particles that, like bullets shot from a gun, transmit the virus to the uninfected. 
The battles we have witnessed firsthand, or on video, over mask-wearing seem to be all about public health, or personal freedoms, or being isolated. But, of course, those are the obvious reasons. So, how 'bout we look at what psychologists are saying: not about the fighting, but the vehemence of the argument?
