Every time that “Argument” happens it’s openly done in biologically unfounded ways by people who simply don’t understand how our bodies actually work.
I'll be the first to admit I don't know how our bodies work, but I think explaining it will be more helpful in the long run than just making the subject taboo and banning everyone who asks it.
At the beginning of the pandemic a common argument against masks was "the virus is too small to be caught in a mask" - which made sense from a layman's point of view. When people started explaining that masks did stop the water droplets the virus needs to be airborne - that argument become a lot less common.
Not everybody who has questions is "just asking questions", if you catch my drift.
