The hate speech laws are just badly written for the online age, which is a problem but they are not going to result in the fall of democracy.

They are catching what would normally be bigoted comments someone makes to their mates down the pub (or maybe in their WhatsApp group) and because it was posted to the world on Twitter it counts as inciting violence.

The police obviously can't investigate all potential infringements so now they have to pick and choose what they do enforce. And inevitably the ones with the most noise get their attention.

The people that do get caught up in this said something nasty they should have kept to themselves. Not something to be arrested for in most cases, but it's not an attack on free speech either. Just a badly constructed law.

Not really sure what "regularly unpersons disagreeable people" means. Shamima Begum is the only one I can think of recently. She got made an example of so a load of copy cats didn't go and join ISIS whose goal is to destroy the western nonbelievers (including the UK). Unfortunate to be made the example I suppose, but it is not a regular occurrence.
