So the assumption is that currently, without instagram for kids, kids are not using social media at all and are not exposed to adult content on the internet? Are we living on the same planet?

I dont understand this, instagram for kids is supposed to give parents more control over what kids do on the internet. How could this make things worse?

To me it looks like, blind oposition to insta kids is largely due to irrational hatred towards facebook (partialy because it is cool to hate facebook now, and partially due to political conformism. As both D and R have found reasons why Facebook is bad to them)
