Not really seeing a problem with the Court's ruling. The intent of adding the question was to help Republicans with redistricting. The Trump Administration was given the opportunity to come up with an alternate reason for why the question was added. They chose not to do so.
If one is not willing to put up a fight in court, then one is going to lose again and again. If anything, they should be taking questions off the census, not adding more on. The number of people in the country has zero bearing on congressional representation per the 14th Amendment. It comes down to how many people each state allows to vote. And that is up to each state. Which is why states are now allowing felons and illegals to vote. It can gain them an extra congressman.
