A current case to reflect on in relation to his politics is Poland. It's controlled by a very right wing, very white nationalist, anti-immigrant xenophobic government yet they've been remarkably welcoming to overwhelmingly white, similar culture Ukrainians. Not that that's a bad thing as they deserve to have hosts as refugees, but the racial overtones of the hypocrisy are unavoidable and very ugly. In the UK among the xenophobes the message is always REAL Brits are white. I guess you could make a case of some kind that it's good to try to keep white countries very white (as Australia did for so long) but you can't credibly be dishonest about it to claim such arguments aren't at the root very racist.
