Of course it is, but like the best jokes it is "funny because it is true".
Some of the mind exercises I lead people through are designed to remap neural pathways. Essentially the mind can "choose" to weaken certain neural pathways and strengthen others. When I use The Movie Theater Exercise, for example, with someone who has had a traumatic experience, the memory of the experience doesn't completely go away, but it does get "buried" (neural pathway becomes extremely weak) and as a result the emotion they experience is also extremely weakened. They can go "dig up" the memory and "revive" it if they wanted to (obviously they're always happy to leave it buried).
In this case, the memory of people who demanded others get Vaxxed or be excluded from society, jailed or even wished death upon them no longer serves any purpose and they'd rather not remember, so they don't. They "bury" those memories, even go so far as to delete posts from their social media accounts. Although, I wouldn't be surprised if certain social media platforms retroactively applied new filters that remove posts just like they did to the anti-covid-vax crowd real time, except no notification and no ban. Not only do the people who pushed the jab want to forget about the things they said or did, the programming they're receiving is helping them do just that.
I know many may be skeptical that the media streams we have coming into our lives are actually designed to program people's minds, but look at the evidence. Look how quickly way too many people jump right on the next social justice bandwagon as if they have become mindless Borg-bots receiving their programming from a central hive-brain.
