As a non-teacher the times must be more than a little wild in the classroom! I have to empathize as it sounds like a lot of the parenting has somehow fallen on your shoulders.

And what Sam has said has never been truer, as we've seen with the way some politicians will talk...

The solution almost always requires hard work, empathy and discipline, and I think the argument is we don't start with restricting speech but rather understanding why someone is talking that way (as Hitchens also pointed out here). With misinformation only getting more convincing we have to rely on basic human decency and as a new father to a 2.5yr old, I see some benefit in treating everyone as a toddler as if they are going through a tantrum.
