There are some art products from street painting which cleverly show opinion of immigration.
A group of grey pigeon refuse a green pigeon staying with them because they looks totally different. It is a true and sad story. Banksy still use his black humor to tell the world and make people thinking.
I think that street artwork is clearly showing problem of immigration. People from other countries do not welcome them. however, there is a mockery on ‘pigeons’ what shows same kind of animals drive their own kind.
