The thinking tends to go something like: "Oh, that's just asians doing things without any scientific grounding out of group think. I know that because I read an article in The Guardian which said that wearing a mask is not a 100% protection against getting infected, so because of that they are ignorant."
The messaging has also become confused by journalist-activists attempting to do some public good by saying masks are meaningless, just so that the public doesn't hoard the masks that the people in healthcare needs.
