Live in the moment, one thing at a time. You should be listening. The logic is simple, when it is your turn to speak people should also listen. Currently they are frantically adjusting their talking points in stead. What does it even matter what anyone says at that point?
Or even more hilarious: At the moment the only media attention these politicians get is about their excessive phone use. What they are going to say when it is their turn to talk I have no idea.
To be equivalently (ok, maybe just a bit more) blunt back to you: if you (as another person who will be speaking after me) care so little about what I am saying when I am speaking that you aren't fact checking what I am claiming and taking notes while adjusting your own talking points, what the hell are you even doing? Hell: what am I even doing at that point? Isn't the goal of this entire exercise wherein we all came together to have a massive meeting that we are supposed to be talking--even "sparring"--with each other in an attempt to find the truth? Your quaint concept of what it means to "listen" to someone else is just extremely strange to me... (though maybe a bit less strange as your final sentence makes it sound like you don't even care what people say anyway).
The point of a parliamentary session is for the general public. All the real meaty discussion takes place outside parliament.
This is mostly down to the low amount if time your average member of the public has for politics giving the news media enormous power over narrative (particularly out of context quoting), which requires the public stuff to be kayfabe.
FWIW, while I appreciate that federal government is pretty broken, it is worth at least understanding that that isn't always how it works, or really even how it is supposed to work at the federal level either: at my level of government, for example, if "all the real meaty discussion takes place outside", that is actually illegal, due to California's Brown Act, which enforces open government transparency; the premise is that all meetings must take place in the public so the public can know the how and why behind decisions, and the public must even be able to interact with the meeting.
