It's always been a bit of a woolly statement.
At any given time 'us' has been everyone who agrees with you with 'them' being those who don't.
It's been the working classes against anyone else.
Well it was until people in suits decided that this was a classless society.
More recently for some it has been the media led UK born against immigrants argument.
In the aftermath of the paralympics I suspect it will be the disabled v the able bodied as the coalition continues to drive a wedge between us all.
They've already being going at it hammer and tongs to separate in our minds the employed and the unemployed.
There's a shifting sands aspect to it that allows them and us to be applied to just about anything.
Yet have the lines between them and us ever been cast sharper now that the truth about Hillsborough has been revealed?
On one side there's the people of Liverpool who always knew the truth, and they've always been backed up by virtually every Tom, Dick and Harry from across the whole of the country because deep down we all knew the score.
Then on the other side is the Murdoch funded Sun who lied, the police who covered it up, and the politicians who buried it.
Now the proof of their complicity has been revealed and it has shown in sharp contrast that there is indeed a them and an us.
There's plenty of comments doing the rounds about how Thatcher wanted the police onside and aided them in hiding the truth for her own ends, but lets not forget that she wouldn't have done this alone.
The whole top tier of the conservative government were happy to dance on the graves of those who died to promote their own political needs.
Disgusting low lives who displayed the same amount of empathy for their fellow man as a sociopath would.
However lets be fair and spread the blame a bit further.
Does anyone really think that the information that has now come to light was not available to subsequent prime ministers and their cabinets?
Every single leader of this country after Thatcher knew the truth.
None of them felt that it was necessary to share it.
Not one single person in government felt that providing closure to those who lost members of their families on that day was a priority.
Not one felt that the tarnished character of Liverpool should be addressed with the truth.
That's the harsh fact of it.
The Sun of course knew from day one that they lied, but lying, or fudging the truth, is their stock in trade.
Why anyone buys that rag and gives anything they say credence is beyond my ken.
Maybe now people will wake up and consider that if they lied in such a hurtful way about the Liverpool fans at Hillsborough then what else have they been less than truthful about?
The people of Liverpool know that if they say the sun is going to shine you need to crack a curtain to make sure that the reality isn't that it's raining cats and dogs.
It's time for everyone else to catch up and consign any overtly manipulative newspaper to the dustbin.
This current debacle so close on the heels of the Leveson inquiry, where Murdoch has been shown to have his grubby fingers in every pie since Methuselah was a kid, must act as a catalyst for its downfall.
It simply must, but it probably wont.
People want their football and tits and hell mend anyone who gets in the way of them.
A little matter of smearing a city and it's people with lies seems unimportant when it may mean that an individual will miss out on a cheap thrill and a poorly written article on transfer windows.
As for the police.
Well lets not paint every rank and file bobby with the same brush, but at the same time lets not forget that there was drastic life ending mistakes made on that day and no one from the time was held accountable.
Worse, that apart from no accountability, was that there was a cover up.
A deliberate move to not accept that accountability.
Time and again the police have been used to limit our rights and the payment for doing so has been that they are often offered a get out of jail free card from those in power.
Hillsborough is a prime example of this in action.
It seems rare for them to pick up their truncheons and riot shields to defend our rights as citizens of this country.
Instead every time I see an image of them doing their stormtrooper tribute act it would seem that it is purely to protect the interests of a minority at the top of the tree.
How did we get to this point?
I've said it before that in the past governments and big business used to pay lip service to us, but increasingly less so now.
Hillsborough is the proof.
In a time gone by they would have been concerned about the public opinion, or at least pretended to be.
Do any of us really see any concern, or even faux concern now.
Every half arsed platitude rings completely false.
Every empty apology an affront to us all.
They don't care about what we think and it's written all over their faces in blood.
So why are we, the majority, continuing with this game.
They have now fundamentally drawn the line in the sand and we can see very clearly who is on one side or the other.
It's them or us is starting to sound more like a challenge for survival.
