Martin Luther King Jr was a believer in the American Dream and the American Constitution which was founded on liberal democratic priniciples.
Read up on any of the founding fathers and their views on propaganda and freedom of the press and they also repeat this about the need for plurality. Jefferson is my fav but he's simply from the same political church as King.
Its about checks and balances to the system and a social contract in which all people have a stake which is equal to each other.
What has happened in recent years is that has been eroded, and you have an increasing number who are disenfranchised from that process and are aware of it and feel unable to challenge it. The idea that the American Dream was something for everyone and that, if they choose and they worked hard, would give them rewards has disappeared.
This has happened to a large number of very different groups. Its come out of austerity - and a stagnation in political ideas and exchange where there is now a dominate grouping which seems to be actively working to shut out others who do not replicate them.
Thus we have hit a crisis point, where the functions of liberal democracy are no longer working and there is no incentive to debate, engage or otherwise be respectful as it feels like other ways to power are more effective.
This is presenting itself in lots of different ways, but the root causes are all very similar.
The only way out of this mess is for individuals on both sides of the political spectrum - left and right - to work towards reestablishing a feeling where liberal democracy itself offers them something. It needs a reawaking of those values.
The UK is part of that - even though we don't have a constitution. We are currently in a time of that crisis where it is essential to make the points we need to and DISCUSS things and feel like we are engaging and getting something out of doing so, in the face of feeling unrepresented in formal political channels. There are numerous political crisis points currently springing up because of a systematic failure, so it is natural that many will seek to exploit this. Politicians can not plug all these holes all at once. Indeed Corbyn's current strategy is precisely about capitalising on that inevitability of the damn bursting, in order to trigger some sort of political revolution. You also have elements on the right under Arron Banks and Leave.EU agitating in exactly the same thing.
However, the question with that for me, is whether thats really a people's revolution as its being framed or whether its more just like regime change, which doesn't benefit the people as a whole.
This is why the need to organise and create a variety of grassroot type groups - on a number of political issues and ideas - not just over the TRA stuff is such a crucial thing in the next couple of years. Otherwise we will end up with something rather ugly imposed on us.
And as part of that, it is absoluetely crucial that we all have a good understanding of how democracy is supposed to work in order to tackle the challenges that social media and viralent aggressive populism present.
