So it is fine if white Republicans are disadvantaged? That's unequal treatment. It seems wrong to see them as a group rather than as individuals. In voting, shouldn't it breaks down to equal individuals with different ideologies, not various voting blocks with equal representation.
Excellent point
For instance, creating school districts where blacks are segregated from whites is bad, according to liberal orthodoxy.
In contrast, creating Congressional districts where blacks are segregated from whites is good, according to liberal orthodoxy.
If you ever find a rational answer from a liberal to your excellent point, please ping me. I still don't understand why segregation is good sometimes, but it's bad at other times.
