Democracy is supposed to be noisy and argumentative. It’s a feature, not a bug. It’s just like the people. If the Americans were quiet and mild mannered (somewhat like sheep), you would have very dull elections. But Americans tend to take things seriously about the country they run. This is a good thing. Remember that except for the Blacks and the Indians, Americans (including Blacks and Indians who migrated here from other countries), left their previous residence because they weren’t content to be sheep, and were annoyed with the sheep dogs, and wanted to move somewhere where they could become wolves, so of course they do a lot howling.
If you want a place where elections are quiet and well mannered, and all the politicians say things that everyone says they agree with, try North Korea.
