Well that is exactly the sort of thing that makes me very irate. Not only is it complete nonsense, it's presentation in media (a video in this case but I've experienced the same thing from books) there is no way to challenge the falsehoods and debating tricks as they occur and so the whole thing simply builds of that which is not accepted from the start making it all sound so reasonable but only because it is going down a false path. and of course a softly spoken voice trying it's hardest to seem so reasonable when reason has been deserted, is also unacceptable
As expected we immediately get to the error of not understanding that we do not vote for parties but representatives for the area. It is this failure to understand that is where the problem begins even if the narrator claims it is something else. Although he does admit to knowing really later but tries and fails to dismiss this fatal flaw in the argument.
In "Realityland", if few citizens have no idea that is their choice. It is not a problem with the system. In any system some may opt not to fully participate, that is their choice.
It is pretending that it isn't a competition on a local level is disingenuous. Trying to claim the opposite is true is deliberately deceitful.
The nation will be run according to the democratic wishes of the people, not an elite within parties, as is being pushed in the video, if folk accept the reality of a local representative and vote for who will push the majority view in their constituency. Asking questions such as, "Which party do you want running things", is compounding the illusion that it is otherwise, and encouraging the largest threat to democracy, the party system.
Also, stating that there is a misrepresentation error, where none exists, is particularly deceitful. It is a debating trick of stating an opinion, often clearly flawed, as if it were fact, in the hope it isn't questioned (which, of course, it can't be in a video or book) and using it as an invalid foundation upon which to build an erroneous viewpoint/conclusion.
But back to the video, given that there are no errors it mean you can sum as many of them up, as much as you like, it'll still equal zero errors.
After all the nonsense regarding representation, it is put to the viewer as a conclusion that the system is broken, when what it really shows is the initial claims were wrong.
If one elects a representative that truly puts forward the majority view in the community then no further diversity is required, democracy has already been served.
And then the video goes back again to the false claim that we have an unrepresentative parliament. Simply not true. The biggest problem it has is, as I stated above, that the representatives must put forward the majority view and not capitulate to the view of some party they joined. Ban parties and the problem goes away.
People happy with the present system may not have found that "their team" won at all. It is ludicrous to slip the claim as if it followed. In fact, as mentioned above, they are NOT voting for a team. They are voting for a representative for the constituency they are in. But it seems some defamers of Democracy continue to deny this.
If you want a system where the process is fair, stop supporting parties and stop insisting all of them should get their members in parliament even though they did not win in any area: ensure all candidates are independent. This wouldn't disenfranchise anything.
And it is an absolutely disgusting claim to say (even if you are merely claiming "it looks like", no one is that naive) that folk who do not agree with the spouted sophism are supporters of dictatorship. Only folk unworthy of discussing things with, would do that. It's the old trick of insulting those who don't agree in the hope of getting folk to think that they don't want to be in that group, better just agree and not think about it any more.
