He's allowed his opinion and if his fans agree and starting wearing them that'll be great.
People here are allowed their opinion, too, so if they don't want to wear one that's great (not really, but there you go).
Masks will become mandatory in public. They've only been trotting out the they-don't-help line so far due to the PPE shortage.
If nothing else, wearing a mask will help cut transmission in those that are asymptomatic but still circulating in public. Or the selfish twats that feel ill at the start of the infection but still go out (like my neighbours).
Yes, they're uncomfortable (how do you think medical staff feel having to wear them all day?). Yes, many people are fuckwits that pull them down to talk (not to mention one I've seen that cut a hole in the centre of it!) or keep touching with hands that are possibly contaminated.
However, if it helps save ONE SINGLE LIFE by lowering the chance of infection it's worth it.
People not willing to wear a mask in public without a really valid reason need to stop and think about the lives lost so far and maybe take a moment to wonder how they'd feel losing the person closest to them to this disease.
