In the UK, there’s a fringe element that usually accompanies a normal political process. It’s not the entire system that’s at stake (it would be harassment), but a particular policy, party, or platform that draws the ire of a particular group of people.
They haven’t got any plans, and have little to no idea about the problems they’ve pointed out. Their activity is part of a lampooning of a situation, akin to newspaper cartoon or an Internet meme (its modern equivalent), and there’s little real value in it.
It wouldn’t be appropriate to make an equivalence between this and pro-Gaza protests for instance, as it’s not the same thing. An example is the trivialisation of the position of Prime Minister, which is the most effective office of state we’ve ever had.
The point is to see the absurdity in taking serious matters with levity if these issues threaten your nation’s security, for example. It’s the idea of seeing Jesus as Brian on a cross every single time it comes up. It’s not as necessary as people think it is.
The activity of modern individuals is obviously their own, as it’s a part of the way we live, but it’s not in line with the way we think about things. The activity inside Parliament, for example, is more of what we need and very unlike the fanfare beyond it.
