You are kind of missing the point - never mind that even major organised religions seem to have issues with actually living by that phrase! It does strike me as being a bit "holier than thou"
But in the case of Millwall, the club expressly stated that their players were taking the knee was not political. Its only hit the media because of "fans" booing.
So its done you fine, from a white persons perspective but you do appear to feel threatened somehow judging by your comments on your other posts - there is no media or authority orwellian agenda or attempts to condition the masses! For a start a lot of the media and indeed the current government are hardly over supportive of the matter beyond paying lip service to "equality"
You do seem extraordinary sensitive about things such as the race and ethnicity of media presenters, seemingly on the basis that this doesn't reflect your world experience, but then you go on to describe your world view as wide. Not sure how it's been "rammed" down your throat either, one can take as much cognizance of these things as one chooses, personally it has never bothered me, but then maybe I don't feel threatened by folks who are different, theres room for all in this world.
Most folk on here are older white folk who I suspect have not come to terms with a multi ethnic society and most likely never will. Not wanting to appear overtly racist, they couch criticism in terms of "it's political" etc.
Of course the fact that BAME people by and large get a worse deal in life and face unacceptable prejudice from white people is "political" after all politics is how things get changed, it was government who delivered the Race Relations Act, but this taking the knee isn't that.
Sure challenge is good but why is this matter bugging people? Those "fans" weren't making a challenge they were booing their own players FFS!
Theres a world of difference between some of the overt and extreme politics that some BLM factions seem to express and a simple symbolic protest that keeps the issue of racism in the public eye.
