The history of discipline in public education shows that the engagement of parents of teachers has changed drastically over time. Some kids doing bad things sometimes throughout history doesn't indicate otherwise.

Honestly i feel like those (except cigs) might be more healthy than phones. Those infractions you are talking about weren't happening 24/7 but in rare circumstances. All of them are forms of addiction.

In no sane world can you compare the percentage of kids engaging in social media with the likely 1% of children that owned porno mags in the 70s.

Your comment is completely disingenuous.
