Why does the topic keep reverting to Romans, East Europeans, Egyptians and whatnot and sexism/feminism?
Why can't people focus on the topic of racism and how they personally can do something?
IMO it's usually expressed in a form under which people can't do anything effective.
Eg in the US unarmed black men are 2.5X more like to be shot by police as unarmed white men (15X in Alabama). Even after adjusting for socioeconomic status there remains a gap, so racism in some form does play a role and there historical racism plays a big role in the difference in socioeconomic status to begin with.
The question is how do you fix this? Police, for them most part, don't believe they are acting out of racial intent and in fact black police officers turn out to be just as guilty as white officers. Give this "get rid of racist police officers" doesn't seem to be a real option.
To come up with a real solution, first we need to understand what it is in police training, culture and work environment that causes the problem, then and only then can we take the steps to do something about it.
The first thing I think needs to be looked at isn't racial in nature at all. While US police shoot unarmed black men at rates 2.5X higher that they shoot unarmed white men, they also shoot unarmed white men 4X as often as Canadian police do and 20X as often as German police do.
The biggest part of the problem by far is that US police culture and training involves making people obey you and shooting them at even the suggestion of personal risk. Fix this authoritarian tendencies would significantly reduce the number of black men shot by police even if the black to white ratio doesn't change at all.
The next biggest thing that could be done is address the underlying social issues that create the difference in socioeconomic status. This isn't something that can be fixed quickly. It's a problem created and entrenched over generations and will take generations to resolve. But, as the saying goes even the longest journey begins with a single step.
The "obvious" problem bias on the part of officers themselves may in fact be impossible to fix while differences in socioeconomic status remain. Human brains are pattern finding machines. If skin color gives real clues as to socioeconomic status (which at present it does) and socioeconomic status gives real clues as to how likely someone is involved in criminal activity (which it does) then human brains will connect the dots when they go out looking for the people most likely involved in criminal activity.
Of course there will be some out and out racism as well and this can be fixed by purging these officers and attacking racism in police culture, but IMO this is the smallest part of the problem in most cases (maybe not Alabama) so the benefit from what many people seem to be calling for would be marginal IMO.
