If you take a look at the demographics of this country, it doesn't make sense for Congress to be 100% white. If you'll have a look at the link I'll add below, you can see what I am talking about as far as demographics are concerned. Whites still hold a majority in Congress. There's nothing inherently wrong about this, they are elected officials, not appointed. People voted for them. If The People decide they want more black people in government, it is not an attack on whites. https://www.census.gov/quickfacts/fact/table/US/PST045217

I am not saying that Congress needs to fully represent the demographics of the country, people elect who they think would best represent them in government. If they all voted white people into office, I would fully support that. As you can see however, over the years people have been electing people who they think would best represent them, sometimes they are white, sometimes they are black, and they can even be Asian! I don't see how you could have a problem with this. Unless of course you think white people do the best job at governing others. Almost as if they are supreme to the other races.
