Unless you're over 65 and/or care about people over 65? Or maybe if you're immunocompromised?
Actually, most of them are dug in because they are incredibly stupid. Knuckle draggers who not only can't spell, but can't type. Can't seem to handle even the most basic of logical constructs. Some of them are considering nebulizing hydrogen peroxide. Most of them think the 'blood of Jesus' protects them. They proudly proclaim "I got an immune system" without seemingly understanding what that is or how vaccines help them. Wearing a mask marks you as a 'sheep' but these obese mentally deficient walking co-morbidities are somehow lions. All independent thinking lions who re-tweet from the same meme factory and parrot whatever Fox is telling them to parrot. Who think "let's go Brandon" is a clever retort.
And many of them combine that incredible lack of intelligence with an astounding amount of hate for any other human being who would dare suggest they love their neighbor as themselves.
And while yeah, some mixed messaging hasn't helped overall, it doesn't really matter. These are idiots who think Candace Owen memes are the way to live their lives. I really had no idea who she was until I started browsing all their entries on sorryantivaxxer or r/hermancainaward. The 'mongering' is all the media they apparently consume 24/7. And at the end, they'll run to the hospital and clog it up (which is another way they are absolutely impacting us, btw) while calling on the 'prayer warriors' to help them before the go fund me for the funeral is set up.
The idea that 'covid fear mongers' (I've yet to see one of these, btw) are causing the stupid to not get vaccinated is a pretty damn flawed idea, imo.
