Can you give a reference to the text you quote? Is it a peer reviewed paper or an opinion piece? What's the date?
If wearing masks caused a risk of really high viral dose from whatever you're already infected with
doctors wouldn't be able to wear them, it'd be a health and safety risk, surely? They'd be getting ill frequently when having to do surgeries hours and hours long?
Early on, several scientists were dubious about the benefits of masks given that people can't be guaranteed to use them properly, and because there was an unproven assertion wearing them might make people less cautious and less likely to social distance. (Not an issue in crowded classrooms - if my Dd's is anything to go by they'd have to be sitting on top of each other to get any closer) Early on, opinion in the scientific community was much more divided.
Since then, more evidence has been accumulated via both experimentation (e.g. hamsters in masked and non masked enclosures - showed that fewer of the hamsters in the enclosure with a mask got ill and if they did get ill, it was less severe) and the 'real world' experiment of the pandemic (e.g statistical analysis of countries which adopted mask wearing early vs those who didn't), and now the absolute weight of scientific opinion is that masks work. They're not 100%, nothing is of course, not even vaccination. But they do have a significant beneficial impact.

I'm not even going to argue with someone using experiments on HAMSTERS as evidence for use on children! Jeez.
