I actually feel that teens shouldn't be on social media at all. But I also don't think I should be able to lord that opinion over other people via fiat.

Sugar is pretty bad for teens as well but I don't think banning that will solve health issues anymore than this will help teens.

Personal decisions > a government trying to be mom

Governments always end up doing the most damage when their control is "for the good of their constituents."

This might seem like a good thing while they're parenting for you on things you agree with, however, there will likely come a time when they do something you don't and by then it will be too late.
