It specifies a large number of people including myself. We don't necessarily fall neatly into any other category.
If I was talking about a similar group of people in America, I'd say "People who understand the Constitution". People who have taken the time and effort to learn about how government works, (or who were made to do so at school - unfortunately, speaking as a teacher, we're somewhat discouraged from teaching our students this nowadays - I wonder why?)
Informed voters. People who actually follow politics in depth, rather than just rely on the soundbites they see on the news. Americans can certainly be forgiven for not understanding the intricacies of the Westminster system - far better that they understand their own and for the same reason.
It's the anti-Israel lobby in Britain that want to make this vote out to be a much bigger deal than it is, because it stokes their ego, and makes them seem more powerful and successful than they are. It's Labour (well, most of Labour - Israel does have some support in the Labour Party, but it's a minority) that wants to make this vote out to be a bigger deal than it is. It's their allies in the left wing media in the UK that want to make this vote out to be more significant than it is.
It's not a tiny matter - it shows that the Labour Party has a major bias towards Palestine and against Israel - but most people already knew that. That could become a very significant problem indeed when they next win a general election. But this vote is being presented by the media as a massive win for that side of politics - in fact, it is a defeat. They couldn't get near a majority in the House even with a whipped vote. That makes the issue a dead letter now as far as the current Parliament is concerned.
Okay, that might answer the who, but how? It seems to be a very subjective POV that I suspect not all share.
