And, it is factually known, that mask wearing does reduce peoples’ oxygen intake by up to 20%.

I'm sure it does. I wear one and have to change my breathing to breathe deeper, otherwise I get just the stale exhaled air.

but covid also reduces the body’s o2 saturation, so if you have it, and also wear a mask, you’re killing yourself to reduce other peoples’ anxiety and irrational fears

Anyone with COVID at that level (low oxygen) should not be out in public.

not everyone who has it knows they have it

so it becomes a worse problem for them

I can believe that. I wore a mask into Costco and was winded by the time I pushed the cart back to my car. The only difference was the mask. It definitely puts a strain on breathing and people who have difficulty already, due to allergies, asthma, or other conditions should think twice about making it more laborious to breathe.
