The crux of the matter for me is what the precise status of the people fleeing the middle east is.
Are they Refugees or Migrants ?
A genuine refugee is obliged to claim refugee status in the first SAFE country they arrive at and must IMO get all the help they deserve after escaping such evils even if that first port of call is the UK.
However many have arrived in Turkey and are deemed to be safe and free from fear of ISIS and their ilk.
Once that refugee decides to continue their journey onward and across seas to Greece, Germany and as many are concerned about ultimately the UK they become (economic) Migrants who have only made the decision to move elsewhere driven by the need for a "better" life rather than the primary need to feel safe.
Whether or not I would risk the lives of my young family for a "better" life as opposed to just a safe one is questionable and I think the motives of those moving around Europe after their original arrival should be examined.
For the record I don't think anything done at a football match or any public arena for that matter would make a blind bit of difference to government policy. They don;'t listen to the "little people", look at the don't attack Iraq march in London, over a million people protesting against it and look where that got them?
