"Respect the shutdown" ??? LOL. Wonder what THAT means. To me, this line of thinking doesn't make sense - "There is no money to pay employees, therefore we should spend employee manpower and physical resources on blocking access to government-provided structures which require little or no maintenance or supervision."
It's a spectacle. They want people to have an impression that their world will come to an end as long as the government cannot operate, even though ironically it's government presence and operation being used to create that impression. Then all they have to do is get the blame to fall on their opposing politicians. Job done.
