Why are people so adamant when it comes to not wearing masks?

This is a response to the question by @888theGreat :
"Why are wearing masks still an issue?"

Honestly, why do people fail to do adequate research nowadays?

Masks are not 100% effective, yes, but are meant to be used in conjunction with safe distancing and good hygiene. They still slow the spread of the virus and reduce the risk of transmission, especially to vulnerable groups.

Seriously. Some people in the U. S. A. are either just plain brainless, ignorant, inconsiderate, or have an IQ of 30.
