"And here we now have government deciding what is acceptable speech"
I had that thought too. What makes trolling trolling? Is it causing offence amnd if not what seperates trolling from simply being offensive? If it's repetition, does that mean when the same clueless poster rabbits on with their pet lunacy post after post, you are now be politely dismissive, or can you still respond in a derogatory manner?
Then I had another idea. The government controlling what you can say is nothing new - they reclassified so many things as "hate speech" now that I'm almost afraid to give an example!
Maybe one day we'll grow up as a nation and realise that people should be free to express their opinion, no matter how upsetting or retarded it may be, while their audience should be free to ignore them, respond, or choose to be upset by it.
