I think many of you have allowed yourselves to fall into a trap. A very common tactic of those seeking power and/or your money is to create a problem and get everyone whipped up into a furor over said made up problem. Of course the same people who fabricated the problem also have a solution to sell you. Stating that 'western' science is racist is the fabricated problem, arguing over the sins of our fathers is a distraction.
I'm sure that there is some truth in that but I suspect it only accounts for a fraction of the people involved in this. More likely motivations are the usual ones in politics - "something needs to be done", "I'd like to shag that man/woman who's speaking", simple tribalism (note that's a small 't'), herd mentality etc. etc.
Like all political lies there is a grain of truth at the core of this. Remember that this started at protests aimed at removing a statue of Cecil Rhodes. I can quite understand why people would want to remove a statue that honours someone that is now, with more than a little justification, regarded as an oppressor. You aren't going to find many statues in public places of Hitler, Mussolini, Stalin, etc. etc.
It's a short, but familiar, step from "this is a statue of a bad man" to "the people who put this statue up are bad", to "anybody like the people who put this statue up are bad", to "all our problems are caused by people who are like the people who put this statue up - kill them all". There's no rationality in that progress of events but it will catch up many, many people who ought to know better. Once you've abandoned rationality to take that first step it's easier to sidestep rationality when you're further down the path. Before you know it you've got a great big pile of bodies, half your infrastructure in flames and you've still got the problems you started out with which weren't anyway caused by a statue of a man.
What I think is notable is that not one of the 'movers' in the video that sparked this discussion would have been born in 1994. Why 1994? Because that's the year that the first universal (i.e. majority rule) elections in South Africa were held. So none of the loud voices being heard there are of people who actually suffered under apartheid. Also I strongly suspect that none of the loud voices being heard here belong to the children of the poor, i.e. those making the noise are already part of a relatively privileged minority.
The turning point, as always, is going from the reasonable, to the small lie to the big lie. I suspect somehow that the speaker has no disbelief in the laws of Gravity, as espoused by Newton or otherwise.
Note that I think there is no difference here between the people who are leading this saying "It's all the White's fault" and the people in other places (and also, but not necessarily, other times) who say that is it all the fault of the immigrants/Jews/blacks/Moslems/intellectuals/commies/liberals/SJWs. As long as there is an easily identifiable group to blame you don't have to take responsibility for your own shortfalls or inability to actually get on and do something about the substantive problems. If the 'other' isn't sufficiently identifiable you can make them wear yellow stars or pink triangles. If they don't actually exist, that's OK, just make them up - (Communists in the State Department). The followers, as opposed to the leaders, are the same as they've always been - bamboozled.
Why is this all worrying? One word: Zimbabwe.
