Race is a protected class but currently it's not illegal to discriminate against political opinions and 'race' is a proxy for those.
> DOJ’s accusations of racial discrimination are baseless. In 2011, both houses of the Texas Legislature were controlled by large Republican majorities, and their redistricting decisions were designed to increase the Republican Party’s electoral prospects at the expense of the Democrats. It is perfectly constitutional for a Republican-controlled legislature to make partisan districting decisions, even if there are incidental effects on minority voters who support Democratic candidates.
If it's a good enough excuse for Texas republicans to prevent minorities voting, then surely it's a good enough excuse to want to exclude white people from your life?

I'm glad you said this. One of the more infamous gerrymanders in the US is in Chicago --- the notorious "earmuffs". You can just look at it and see that something's hinky.
But what's really happening there is that there are in fact very well-defined Latino neighborhoods in Chicago, and the earmuffs capture a bunch of them neatly: Pilsen, Little Village, Cicero, Belmont-Cragin. If you know Chicago, you know these places, and you also know what the boundary between, say, Belmont-Cragin and North Austin is like; however artificial it looks on a map, it is a real border. That these communities are where they are is also not purely happenstance: a lot of very unfortunate social engineering took place in the early-mid-20th century to put those neighborhoods (and all the other neighborhoods) where they are now.
That's not to defend gerrymandering writ large, or even necessarily the earmuffs, but just to second your point about the complexity of the problem.
