Well, NASA needs to know about food. They send astronauts to space and have to give them proper food. I'm sure NASA know a lot more about food than most people do.
Yes, in the ideal world NASA would be hiring the best. But they don't live in an ideal world. They live in a world full of bigotry, where people are born into situations that give them a huge advantage or disadvantage, and race plays a part.
People are trying to make things more equal, and yet there are those bigots who don't want things to be more equal.
When it comes to being gay, it's none of anyone's business who someone sleeps with (as long as it's consenting adults) and yet it becomes a HUGE part of the electoral process when the right start using "family values" to attack gay people.
You want NASA to get on with its job, then stop ******* around and attacking some of the people who end up working for NASA just because you don't like what they are.
No, the US needs to change. The bigotry needs to be attacked so that kids grow up tolerating others, not learning to be bigots so they can train the next generation.
