Racial voter suppression in the US

Content warning: institutional racism.

Recently, elsewhere, I commented that the US 'suppress[es] votes by criminalising being black and requiring voter ID'. I didn't think it was controversial to say the US is institutionally racist. An abhorrent fact, yes, but not controversial. Apparently it is. Which led me to think about what I meant. Comments/challenges welcome.

This seems to be quite clear evidence of racial voter suppression and that black people are disproportionately criminalised.
