Why are Americans like this If there's a lot to talk about, just stop at 7pm (or whatever) and continue the deabte the next day. Better yet, have proponents and opponents pick a few specialists like a debate team and let them debate while the whole chamber listens.

Legislatures in the US keep doing these dramatic gestures of legislative action, but hardly anyone has time to listen to it all and they don't listen themselves, very often you find your representative has been giving passionate speeches that look/sound great in campaign ads...to an empty chamber. In many instances, the process is gamed to the point of being a scam on the voters at this point.
