It would not surprise me if they are going for soft targets. That, and Mayor Khan being a mask enthusiast who wants to look like a hero.
As a complete aside but about situations like OP mentioned in Post 1, a lot of videos that I have seen of those complaining about others not wearing masks has come from those who wear the flimsiest, leakiest ones. It would be more than a bit amusing to see them told that their mask was not really good enough and maybe even worse than useless; perhaps they might also change their tune when they begin to understand how about 95% of masks were not designed to stop airborne viruses as well as false reassurance effects in general.
Indeed; the argument for mandating other people wear masks goes along the following likes: "
I wear a (flimsy, loose fitting) mask which is not designed to filter aerosols, therefore I am not protected by my mask. Although I have been vaccinated, I do not trust the vaccines and therefore do not wish to be exposed to aerosols containing virus particles; therefore I require you to wear a (flimsy, loose fitting) mask, in case you are infectious, so that any aerosols containing virus particles are reduced by your mask"
The argument goes that flimsy, loose fitting masks which are not designed to filter aerosol particles, somehow do filter such particles when exhaled by the wearer, but do not filter such particles for the wearer.
This argument is of course as flimsy as the masks themselves; the argument is full of holes, just as their masks are.
Now they could wear a tight fitting, highly effective FFP3 mask, which is designed to filter aerosol particles and offers almost 100% protection. But they choose not to do that, because it would destroy their argument that others should wear masks, given that their argument is that masks which do not filter virus particles do not protect the wearer.
People who are genuinely wanting to avoid exposure to virus particles would wear tight fitting FFP3 (or almost as good FFP2) masks and would keep their distance from others; they would be highly unlikely to get into a fight with someone.
How do we know this fight was started by a masked person and not someone who takes exception to people wearing masks? Plenty of those people about and wouldn't be the first time.
We do not know who started this fight but all the arguments and aggression and inappropriate comments I have witnessed have all been made by people who have been wearing masks (as others have said, it's always those wearing flimsy loose fitting masks, not highly effective FFP2/3 masks) directed at people not wearing masks. And I know from discussions with other people that many others have witnessed the same.
