It’s a “reality” they wish to believe in. If they pretend hard enough, ignore actual reality and make enough excuses when it slams them with the consequences, they can still cling to that narrative. The heart attacks, myocarditis, cancers, shingles and myriad of other resultant ills will be “explained away” - until they can no longer be denied. They don’t want to believe that these drugs are dangerous and so they pretend that they’re not. There are different kinds of intelligence and your pal sounds as if she’s lacking in emotional intelligence. It’s childlike, but far from endearing. I’ve got liberal friends just like her. It’s very sad.
