Why hasn’t Halloween or cosplay been banned then? Why don’t we keep all children wrapped in a bubble?
Halloween and cosplay mask are voluntary, and the wearer can take them off at any time if they are uncomfortable.
When I was a kid most of the time my mask was face paint. I also recall that most of the kids walking around with the plastic mask wore them as hats until they were on the porch about to get their candy.
Walking door to door is hardly strenuous for a preteen particularly at the end of October with cool fall temperatures.
Cosplay usually is also a relatively sedate affair that happens in air-conditioned comfort. Walking or sitting around a convention center where the participant is free to remove the mask if uncomfortable. I don’t follow cosplay personally. I wouldn’t be surprised it their conventions have been cancelled during this false pandemic.
The athletes are going to be reprimanded if they remove the mask. Refusal to wear the mask means exclusion from the activity.
