I suspect that the majority of the UK population don't want to take more refugees/migrants. Still, why let democracy get in the way, eh?
I'm not in the UK so can't speak for them but the Irish especially with our history of forced emigration when we had to flee the famine to the US because Europe's borders were closed to us should be a kick up our holes to do something and help.
I often think of the Choctaw Indians who, only 16 years after there own trail of tears and in the midst of their own poverty, raised money to provide famine relief in Ireland. We still owe them a moral debt that can only be discharged by our own humanitarian action towards others in need.
It's alright if you don't feel that need or compulsion to help. You're not in a minority.
