Because he is a European correspondent, or because he lives in Brussels?
Kate Adler is a European corespondent for the BBC (now), and has lived in Vienna (where according to your theory) she was a right wing musician, then she moved to Berlin, where she (according to your theory) became an ardent Angela Merkle supporter, then she moved to Madrid, where she became (according to your theory) a bull-fighter, then she moved to Jerusalem where she became (according to your theory) a Zionist, then she moved to Brussels, where she became (according to your theory) a biased remainer.
You do make some very stupid assumptions.
I wonder why that is.
