Migrants from various troubled areas of the world have found a home in the UK when other countries may well not encourage them to settle in their country. Similarly Nudge has been thrown out of his homeland, the BBS, which had become hostile towards him. He has found a home on Tykes Mad when other boards were less welcoming.
Seems like a good analogy to me and not in the least racist. The PC Mob try to find racism everywhere. They will be saying next that posters should "take the knee" on the carpet with others in the house clapping before they begin to post anything.
I signalled my virtue by taking the knee before posting this but, at my age, it took me heyf an hour to gerrup ageean with help.
