I've noticed that some people who don't have personalised social media seem to assume that other people do because they're mentally deficient or ignorant.
It's the same as how unsympathetic people ask why fat people don't just stop eating, or drug users stop getting high, or the cyberbullied don't just turn off their phone.
It's a lot more complicated than "just don't use facebook".
But parent is not talking about calling out people for having social media accounts. He/She is talking about those having a social media account judging those not having one as paranoid. You've just propped up a straw man here without addressing the point the parent comment made.
