To me, this is not just about racism, for that undoubtedly plays a part in some peoples' thinking and opinions when this thorny subject is raised. It's as much to do with broken promises and incompetence by politicians and the relevant authorities as by outright racism. People have had enough.
Yes, the UK is a signatory to the UN Convention relating to refugees, but there's a significant difference between the genuine asylum seeker and the social migrant who is simply seeking a better standard of living.
I simply cannot believe that the UK is the first port of call for any of these people. And that fact is just as valid as are our responsibilities under the above UN Convention.
Whatever became of the international agreement on "safe third country rule"? Is the UK their first port of call? The obvious answer, unless all these people have travelled a very circuitous route, is "no".
Can anyone seriously justify the fact that the several hundred thousand immigrants/asylum seekers referred to in the link have all met the required criteria? I think not.
