I saw that when the England team (NOT the English team, Steve is quite right!) 'took the knee' in Budapest, many Hungarian children booed.
I actually very much like to see footballers taking the knee. It's a lovely way to show solidarity against racism.
As people on this thread have mentioned commercialism and Tesco etc., I wonder if I 'took the knee' at the checkout in our local Tesco, they might reduce my bill?
(Then I could afford to buy yet more crumpets.)
