I posit that the House is a mess because the nation is a mess because a LOT of people get misleading, or false, information. It's not that they are bad people, they are just misinformed. Garbage in, garbage out.

Though there are a few that can't handle societal evolution, for one reason or another (e.g. religious dogma vs gay rights). Those people aren't necessarily misinformed, but just have a different position on gay rights, women's rights, etc. And, occasionally, they ask hard questions that defy simple answers (e.g. how young should we allow transitioning, and who decides).

But mostly it is misinformation feeding hysteria, and in extreme cases, riots (like Jan 6). The House is a reflection of the people who vote.**



**And a bit of how a 2-party system works. Often only the extremes win primaries, so you end up with polar opposites in the general election, and most people are somewhere in the middle having to pick what they deem as the "least bad". A parliamentary system might have been a better choice.
