Eno seems to have walked some of this back, so my apologies -- he was initially positing a Brexit/Trump "they'll burn it all down/hard reset" mentality a few years ago which even then was not a great look.
From musicians I've talked to who know the situation up close, Parker is definitely on some anti-immigration Brexit trip and has been for a while. Now of course one can say they are anti-immigration but not anti-immigrant. However, I don't think one can really back up a stance where populations aren't welcome but "this individual over here is okay." And yeah, I know we're veering plenty close to full-on politics here, so I'll leave it at that. Parker's music is wonderful but I can do without his worldview.
(oh, and apparently don't get EP started on 9/11, according to a friend of mine)
