Groups and organizations tend to address the issues and/or problems that affect them most. So perhaps your argument shouldn't be that there is a difference, but that they should also address those issues you brought to the fore. Yes?
That's not productive if "civil rights" means different things to different groups. Civil Liberties apply to ALL. And if the causes of grievances are not truely racism -- all this is better addressed from a BROADER coalition of interests.
Lets look at asset forfeiture for instance. Entire black community in the Deep South is raided by BATF and DEA and FBI. Town is dirt poor and 99% black. COWS are confiscated without trial. Tractors, farms and money is confiscated without trial. Entire TOWN is ransacked because of alleged drug violations.. We could on about how urban black communities are targeting for eminent domain because they are a cheap target. But it's not PRIMARILY a race issue is it? Although when Sharpton or the NAACP picks this up -- they re-brand it as "environmental justice" with a DISTINCTIVE racial overtone. Not MY preferences bud. I'm on board with ALL of this. Not just the stuff YOU want to paint as racial or Civil Rights.
Are those previous examples a Civil Rights issue because of RACISM -- or is it a larger Civil Liberty issue? You made it sound that I was some kind of primadonna only caring about MY hide. But true Civil Libertarians are working these abuses for the benefit of EVERYONE. And a lot of credibility would be gained by "black causes" if they spent less falsely claiming that most of this abuses are racial --- and not universal crime, justice, and fairness issues.
