There's lots of theories about why it is. Maybe it's the internet, it's parenting, it's smaller family sizes—people don't have as much biff with their siblings—who knows? But one thing that would make it much, much worse is if this Parliament decided to start legislating what can and can't be said based on the subjective criteria of offence, because once you can be punished on subjective criteria for your political views, we no longer have freedom of speech and conscience. We no longer enjoy the humanity that each of us has the right to think our thoughts and express them so long as we don't incite or threaten violence. We have mob rule. Minorities should care about this, because people who are popular and in the middle don't need free speech. It's those who are different who need to call on its defence and have done throughout our history.
