Just like you, raging, I have no idea what every individual Millers player thinks about taking the knee.
Given that taking the knee seems to have been universally observed over every football league (I'm happy to be corrected on that as I haven't checked) isn't the better question whether it is fair to assume that every player in every league shares the view that it is a course of action that they want to take? That, I would suggest, is an absurd proposition. There are likely to be some who hold racist views, for which it is difficult to hold any sympathy, but are you really suggesting that there won't be some, if not many, who have no issue with the notion of seeking equality for all races, but think the knee gesture is just that - a gesture, or who feel uncomfortable with the stated aims of elements of the BLM movement?
The point I am making is that players don't really have choice. A player who took the view that he would prefer not to participate would suffer horribly at the hands of John's court of public opinion as the left wing twitter mob lit up their keyboards. He would risk abuse from supporters, loss of sponsorship and possibly even actions at the hands of his club. Is that really something that any society should desire for someone simply for swimming against the tide of left wing orthodoxy? I don't think so.
I know that you will rail against the notion of a left wing orthodoxy, but you can see it in action on this board. A couple of weeks ago, I suggested that the officer involved in the shooting of Jacob Blake should be judged in a courtroom as opposed to on social media and was accused of 'siding with right wingers, (or something like that) by Wan Chai. Seriously? Is that where we want to be? Roly cannot tolerate any opinion that does not accord with his own, which he picks up courtesy of his politics.
You say that people who work ‘closely with black people will be plenty aware of why so many of their black work mates feel strongly about the movement and want to show their support’. With respect, that is why I selected the Courtney Lawes link. He IS black and has a number of black team mates at Northampton Saints. Despite that he has been brave enough to stand up to the orthodoxy and has suffered for it.
I'm not suggesting that Lawes has a monopoly on common sense, but he has an awful lot as far as I am concerned. Here's a slight fuller article:
