Nope I gave other options as well.
Right lets put this simply, what do you genuinely believe the motivations are from these athletes/sportsmen and women? They can either be supporting an anti racism stance, they can be supporting a black power message in respect of black people being powerful and that they shouldn't be subject to inequality so a similar stance, they support those who have set up a political agenda under the BLM banner, or they are saying black people are more powerful than others. The problem with the last two options are that the only statements from either players or clubs have clearly stated it is the first option and I've not seen one single person within UK sport say otherwise.
Where as people booing are either doing it because they think these players are doing it for the last two reasons above despite being told this is not the case, so ignoring what they are being advised, not sure why they would be doing that but sounds a bit stupid and ignorant to me, if I was going to boo someone/people I think I'd know what I'm doing it for. They feel bored by an equality issue which makes them ignorant and I don't see this happening when there are other shows of respect or solidarity such as when a minutes silence is held so if they can respect that... why boo? It seems unlikely. They don't believe in racial equality, which makes them racist, they don't like black people which makes them racist....
I've seen barely anyone mention the raised fist being the reason, think including the two on this thread it's a total of three. The one on social media mentioned the 68 Olympics as an answer, my reply to that was to advise him the US Olympic committee have admitted they were wrong to have removed their medals and reinstated them, so history within sport has a president that it's seen as a valid protest. Whereas I have seen hundreds of comments on social media stating it's due to BLM Marxism, where myself and others have questioned them what Marxism is and what aspects of Marxism they are against, I've not seen one single person be able to answer that question, the few that have tried haven't described Marxism in any shape or form, so why are they using that term? Seems very odd to use a term you don't understand and as the majority didn't even offer up their explanation, a lot of these people must know they had no idea why they were using it, why would someone offer up a phony reason to support the booing, there might be other reasons but the obvious one to me is that they are trying to hide their genuine objection to an equalities statement is they don't like equality... which makes them .... drum roll....
