Well, I suppose they might have been that day when they made their protest in the Commons chamber. It was a visible reminder that we are preoccupying ourselves with Brexit when the entire future of our planet is in doubt. And it was quite funny watching MPs trying to maintain their composure and keep their faces straight.

But the recent spate of protests by the climate change campaigners are doing their cause more harm than good. Ok, so they get attention, but what on earth is the point of gluing themselves to trains, for goodness sake?

I thought public transport was a good thing. Obstructing it, potentially making low paid people with not much power in their workplaces late, is neither big nor clever.

And holding up the traffic might grab headlines but it doesn’t do much for air quality in the vicinity.

The powerful message of children walking out of school to tell us to secure their future is so much more persuasive.

And I think Extinction Rebellion went a bit foo far yesterday by attaching themselves to Jeremy Corbyn’s house. 

People’s homes are off limits for this kind of stuff, whether there are politicians or heads of companies. If you want to protest go to their public offices. Nobody’s family should have to feel like they are under siege.

Back in 2012, UK Uncut organised this mass protest of 400 people outside Nick Clegg’s house, a move I criticised at the time.  

The Clegg family was not home – but what if they had been? What about their neighbours? Whatever you might think about Government decisions, politicians’ partners and children should not have had their lives disrupted.

Imagine if they had been home when these 400 people descended? The children are 10, 8 and 3. To a 3 year old, people outside having a go at your daddy, however nice they think they’re being, could be really scary, the stuff of weeks of nightmares.

Now, note that I am not saying that such protests should be illegal, but with rights come responsibilities. UK Uncut have done their cause no good whatsoever this weekend – and that’s a shame because when it comes to some of the welfare reform cuts, as you know, I agree with them.

UK Uncut will have had to have distributed Nick Clegg’s private address to a fairly large number of people, for a start, the 400 there and anyone they tell. How can they guarantee the conduct of every single person who would turn up. It was ok this time, but at some point, if this continues, someone will turn up with malevolent intent.

And that was before an MP was murdered. In the current, febrile climate, when you have emboldened fascists taking to the streets, going to politicians’ homes is not a good look.
