Talking to her is an absolute waste of time. Look into the psychological phenomenon of mass formation or mass psychology, a significant part of the ( Western, at least ) population have effectively been hypnotized and will absolutely sacrifice to an extraordinary degree if they believe it will benefit the very narrow cause they've been hypnotized to focus on ( ie beating covid ).
And I do mean to an extraordinary degree, there are those walking among us so deeply entranced they will whitewash their perfectly healthy teenage children straight up dying within 24 hours of taking the first/second/third/fifteenth shot by claiming it either wasn't because of the shot ( which the man holding the watch claims is 1000% safe ) or that it's okay because they died doing what was right.
I likewise have a friend, with a history of heart problems, who felt the worst he ever felt after the first shot and apparently has zero doubts about getting a future booster ( he didn't get a second because he caught muh covid and that was enough to get the coveted green sticker ). Just lunacy, no other word for it.
