Posting this here because I don't want to distract from any debate needed on the discussion thread about political topics in submission text:
There are some obvious ways to point out that the US is uniquely oppressive in its handling of criminal justice issues, mainly that we have a significantly larger share of our population in jail than most other countries, and there do seem to be components of this with racial implications, eg criminalizing marijuana differently from tobacco. I also appreciate the argument that people should be willing to say "black lives matter" as opposed to an insistence that "all lives matter" as "all lives matter" distracts attention from the immediate issue with respect to disparate policing. However, at the same time I find it impossible to support most of the organizations trying to affect change on the issue.
The organization using the name "Black Lives Matter" seems to believe that they are oppressed mainly by police killings and "Western nuclear family" structure, and uses the word
comrade as if they support communism (which is not helped by frequent use in current left-wing movements of the black power fist, which is itself tied up in socialism). This evinces extreme political opinions unrelated to the problem at hand, some of which are even directly contributory to the problem itself (there is scholarship from virtually every angle in conservative. liberal, and academic sources that the nuclear family is a strong predictor of children staying out of crime). Separately, the rate of state killings of citizens in the US is much less unique than incarceration rates. While it's certainly unreasonable to argue that our level of incarceration is necessary to maintain our unique prosperity, the same is not quite as obvious for shootings. There's a very straightforward argument that our 2nd Amendment uniquely protects us from government overreach, leading to a need for police to carry guns in equity with private citizens, which in turn leads to a necessarily higher rate of police shootings. I think that's a good assessment of the present situation but there are solid counterexamples of the value of gun protections like Sandy Hook.
Additionally, there is
good evidence that using the power of the federal government to require private actors to treat people equitably across various protected class distinctions (race, gender, sexuality, etc.) has had a negative effect on real-world equity. The common example cited is the effect the Americans with Disabilities Act had on the employment rate of people with disabilities. This is similar to the concept that affirmative action in US higher education has had net negative effects on educational attainment. Further reading on this subject is available from minds like Thomas Sowell, Clarence Thomas and (less seriously) Charles Barkley.
All this to say, there is plenty of reason for people who support black lives in America to disagree with the political goals espoused by protest movements like capital letters "Black Lives Matter."
I hoped discussion could continue and perhaps the new shader split into a different option if preferred, but the PR was merged immediately.
