They planned a peaceful protest

No they didn't. They planned to shut the M25, one of the busiest motorways in the UK. Shutting that would force traffic onto all the roads around it, progressively gridlocking the entire south-east and causing misery for at least tens of thousands of people, and I wouldn't be surprised if it ran into six figures.

There's nothing peaceful about a massive DoS attack on the nation's infrastructure.

BTW before you bleat about protest being banned in the UK, no it isn't. Peaceful non-disruptive protest is enshrined in law and everyone has the right to protest about anything they want. What protesters don't have the right to do is disrupt the lives of those around them or to try to force the nation to capitulate to their demands by holding the country to hostage, which is exactly what those JSO wankers are trying to do, and is why they are so hated by so many people in this country.

JSO's message may well be 100% correct. It's not the message that's the problem, it's trying to force it down everyone's throats. You know how much you hate vegans and evangelical Christians? Well JSO is both of them put together on steroids.
