As so often Kenan Malik hits the nail on the head:
'We should oppose the demonisation of migrants because it is the moral thing to do. We should also oppose it because not to do so opens the door for the curtailment of all our rights, and makes it more difficult to build solidarity against injustice, whoever may be the target'!
If you want to know how politicians see us all, just look at how they treat the vulnerable (in this case, migrants).
