My knickers are in place, thanks for asking. Given the uproar over the booing last Saturday, no referee is going to dare to book players for taking the knee and raising a clenched fist, in case that referee is accused of racism (such is the hysteria of the debate).
It's simply that if the racial equality movement want to take people WITH them, it's unhelpful for its supporters to use it's gestures to mock and provoke people, as Chair and BOS did last night. My view
Or they believe the gesture is a powerful statement that they oppose racism and they won't be silenced because some people want to assign a non existent agenda? Why would a referee book a player for that? Seems very odd.
