Banksy is my favourite contemporary artist.
(I'm not posting this as a particular political statement and in fact I have worked on both sides of this particular wall and hear two perspectives. And my own government has had policy walls to exclude vulnerable asylum seekers for more than two decades. No offence intended to any particular nationality or ethnicity. I simply long for a more compassionate and kind world on all sides.)
I think of those excluded today... from family, friendship, the company of others, social acceptance, work, a decent wage, housing, dignity, justice, being listened to, respect... That's it really. This is what it can feel like.
