Masks do not drop your oxygen levels

If you don’t think every damn thing has been politicized to insanity. I posted a doctor showing masks don’t nagatively impact oxygen levels. Which duh, doctors, nurses, nail techs, people who paint/sand, use them without passing out daily. I didn’t even tell people to wear masks.

I didn’t call names or take away any choice or say there are no downsides nor exceptions. I didn’t say anyone has to. I didn’t even say it prevents the spread. Just answered that one aspect and I’m BOMBARDED with bullshit.

To be clear I am pro mask. But people came out of the woodwork acting like I am holding them down and forcing them with this.
