As opposed to the stance (admittedly also ideological, but I agree with this one) that facebook and all its subsidiaries should gtfo children's lives.
Back when I was a kid and dinosaurs roamed the earth, we made after-school plans in 4th period math, because we were all in the same class. If my friends suddenly started making plans in a class where they knew I wasn't present, I'd start questioning whether they were really friends.
Yes, platforms can influence social interaction a lot - but ultimately, regardless of age, we're all still human.
I think most people learn to understand what's fair and unfair in terms of inclusivity, even if it takes longer in some situations. We'll figure out better solutions.
Being a kid without friends because your parents sucked at teaching you how to integrate into society, is very very hard. And allowing your children to be part of other children's social lives, that matters. Even if that means joining shitty social networks.
Does that situation suck, yes. But don't put this on the kids. Please don't make children suffer because of your views on an idealistic society.
