no dog???
you just proposed banning all single men living in certain countries from the UK
As mentioned in an earlier post - "in the current climate".
This countries currently a melting pot and it'll only take a spark to light the fuse.
Let me give you an example - if 10,000 scousers move to Tokyo and just say a small pocket of around 20-30 of them are involved in high profile crimes in the media such as murder/rape/paedophilia with the victims being natives - a lot of Japanese residents will start getting agitated over scousers moving there based on the actions of a minority (look at the reputation of travellers in the UK).
That doesnt make Japanese people racist gammonheeds as the left love to label people - its a simple tribal/cultural reaction thats steeped in our evolutionary makeup.
Unfortunately our policy makers have no understanding of basic human nature instead they're driven by left/right think tanks - so during a period of heightened tensions such as these I think it would be rather sensible to not permit hordes of lone men from high risk countries into deprived areas unless you want civil unrest...
