I wonder what do you mean by it?
Because, just as well, there's an aggressive collectivist movement which directly attacks individuals (and individual choices).
It's really easy to switch from "I like to do my things alone, let me be" to "society is evil" after having been made a pariah by the "collective".
I am not sure I agree, but I think it is an interesting thought worth exploring further.
I feel like this started with reality-tv which predates social media by a few years. I think reality-tv took poorly-behaved and uninteresting people and elevated them. I think this not only normalized bad behavior but even celebrated these people as special. It seems like this just primed the pump for what came after with social media. TikTok/FB/Instagram et al, seem to enable and encourage everyone to star in their own reality-tv shows where the mundane, banal and uncivil are treated as interesting and worthy of attention.
