I don't think this is at all conscious, but I think that the pictures we are seeing are genuinely resonating with the West because of the fact that they are Europeans and white. It's horrifying and makes us feel that war is very close to home.
Like it or not, the prospect of UK refugees from Middle Eastern and African war zones divides opinion. There are many firmly in the camp that they are not our problem or that we are full. I sincerely hope that seeing neighboring countries to Ukraine taking hundreds of thousands - if not millions - of Ukrainian evacuees will stop people bleating on about how we take our fair share.
