In the US, we can express our displeasure by demonstrating or speaking out. These pols have done nothing but exercise that right that so many have died for. I find that quite American, not bigoted.
In 1948, a group of Democrats who rejected President Harry S. Truman's civil-rights program revolted against the civil-rights plank adopted at the Democratic National Convention, and walked out of the Convention. A conference of states' rights leaders then met in Birmingham and suggested Gov. J. Strom Thurmond of South Carolina for president and Gov. Fielding Wright of Mississippi for vice president.
Of course, they weren't "bigoted," but quite "American," according to a "Principled" analysis.
