Zack’s real name Drone
Thanks, having now looked him up I see he was christened David Paulden but changed his surname to Polanski which was that of his Jewish ancestors who escaped Nazi Germany.
Zack was chosen from a Jewish character in a book, which does seem a little unnecessary, but harmless enough and of no consequence.
I also couldn’t really give a toss if Stephen Yaxley-Lennon chooses to call himself Tommy Robinson, though that choice does have undercurrents of a wish to get-on-down with the proletariat.
