Good points, well made.

I find it interesting myself how many people say they would emigrate in a heartbeat, but rail against people from outside the UK who are trying to do the same thing.
They all make sense but the counter points are also understandable or empathetic at least.
It all boils down to the way you put something in another thread or forum as it may have been, resources.
All wars as you said are ultimately about resource and penultimately about religion etc. In this case it's just the same really IMO, it's about resource at the end of it all really.
Countries like Australia and such if Brits choose to emigrate there then they need to bring a skill set in demand, or you have zero chance. Where as The UK is open right up because of the EU, lax border control and easyily abused asylum rights, it's a different kettle of fish really.
We have to have some sort of control and as it stands the control is broken.
I don't think any one here is an out right xenophobe (I am not implying any one is accusing that either) but the above examples although perfectly correct on a human/moral stand they are certainly not the most practical.
We must fix our asylum system to allow those that need it through political or religious persecution, such as gay men from Iran as example who are being deported from The UK to face certain prejudiced, incarceration or even death under law. People who dared speak against totalitarian states and government etc. But Cents original post all be it less than accurate does carry a weighted amount of satirical point that is needs addressing, our system is wide open to abuse.
