Yes definitely, and this particular lesson is proving to be quite difficult! I've also had the experience of sharing information which is then completely ignored. I don't even bring it up anymore, I can see there is no point, it won't change their decision at all.Sounds like my own mother. I recently sent her this excellent video (in Spanish) which explains the current covid vaccines and their dangers in detail. It's full of facts, it's very rational, and it comes from an actual no-nonsense scientist. She watched it and commented it was very interesting. A few days later, she announced she just got the first shot of the Pfizer vaccine. My brothers, who didn't bother to watch the video I sent them as well, cheer. One of them said he and his wife rushed to the US to get their first shot as well (not available for his age group in my country yet), and that the Pfizer so-called vaccine is the best one.
Since then, I make an effort to avoid the subject, since my mother has already made her choice and I had already repeatedly said what I thought about it, so by now it's totally pointless. But in conversation someone mentions the case of an elderly man who got very ill after taken the vaccine. My mom comments it's probably just a coincidence. Yet she has also commented on cases of people who had covid, recovered and a couple of months later got complications from something else and died, that it was a 'covid sequel'. No coincidence there. Because, like you say, Official Culture. She watched it on TV, so it must be true. What Officialdom says has more weight than fact-based arguments.
Luckily, no one in my family who's had the vaccine has had any adverse reaction yet. But who is to tell what will happen when their immune systems react to a real virus, or what autoimmune conditions or cancer or whatever await down the road?
Ultimately, I think it's about free will and personal lessons. You can't force anyone into anything good, and our own lesson is to accept that.
It really is hard to see, yet we're supposed to be seeing reality as it is, and I guess seeing our families and friends willfully avoiding anything outside the official narrative is part of that. Painful though it may be, the hard truth is that they have chosen to ignore reality and nothing we do will change that. They will do what they will do, and that is their free will choice, so somehow we have to get past our belief or hope that if only we found the right article, the right information, they would then wake up. I think we are past that point, if they haven't seen through this facade after a year, they probably aren't going to and what's more, they don't want to see through it. So yeah, in the end it's all about respecting free will.
