It's really amazing how you point to one fucking instance of gerrymandering, and it was about black people, conveniently ignoring that the majority of gerrymandered districts ended up as such specifically to disenfranchise black voters.
That's the point of putting all minorities into their own districts though. Shove all the blacks or hispanics into one little group, so they don't vote with white Democrats in a mixed geographic area and make a majority of districts competitive. Instead all the minorities elect 1 or 2 Democrats, and then 5-6 (for example) districts elect a Real American Republican and continue to control congress.
There is also an argument that having a majority of minority in a district allows them more equal representation, since its more likely they put someone of their own race/background into office. Of course I think a majority of Americans (who aren't batshit racists either way) would prefer someone who cares about their interests over the color of their skin though.
Also not reading this thread, but please don't equate American citizens with American police. There is a huge, and growing disconnect between the two. You don't have to tell an African-American about it, they've been on the forefront against corrupt police forces since the 60's with all-out race riots in many major cities. Nowadays, cops are growing more brazen and antagonistic against almost all American citizens, if they dare to not comply to their every whim.
See this is why Europeans have a superiority complex when it comes to gun crime/control; 'internet Americans' give the impression that you're all sister-marrying red-necks who masturbate to images of guns on your wall, and then jizz right down the barrel of your nearest gun and say 'OH shit, Ma gun!!!' and haul your pants back up, take the gun apart and start tenderly cleaning it, then start to get a little bit excited in your pants again as you clean the inner workings of your gun, so whip your dick back out and start rubbing it up and down the outside of the barrel again.
Yeah. I love reading comment sections on all sorts of stories about American politics. Just keep in mind the majority of people posting are 70+ year old retired rednecks who spend all day "trolling libtards" over anything.
