We need to allow for civil discourse between people we disagree with, or else we'll form an echo chamber.
It's just like when people quote the percentage of black people in prison as some kind of proof of inherent black immorality. They are ignoring the root causes that aren't the fact those people are black: average wealth, systematic racism, etc...
The comment is getting down voted because it's just logically stupid - it's like someone coming to you with the problem that they don't have any food, and you going "Well, you haven't eaten a meal all week! Maybe start there." - it's not useful or a "counter", it's just restating the problem and pretending it's the fault of the victim.
Compare that voting figure to the national average for people in a similar socio-economic class to the average black person, and then consider they are having votes suppressed as well. Not to mention a political history of being ignored, discriminated against and lied to that would likely reduce anyone's faith in the system.
The idea that it's somehow their fault they are being targeted for systematic suppression or that we shouldn't care about the issue because they, as a population, have low turnout, is just flat-out stupid.
In 2017 in Alabama black people had an amazing ~30% turnout for the senate elections. More than for President Obama.
I don't think requiring ID is a real issue in Alabama.
