My senator doesn't have a number you can call to talk to an actual person. When you call you get an automated message telling you to fill out a contact form on their website. When you fill out the form all you get is an automated response telling you how the senator is fighting for your rights as a citizen (not even acknowledging that you contacted them) and as a bonus you get signed up for their political bullshit newsletter. If you go to their office, it's behind security and multiple locked doors that you can't get through unless you have an appointment. To get an appointment you have to call the office.
When the maze is only dead ends, why is it surprising that people disengage?
Nobody said its surprising. Everyone knows this is on purpose. That's why it's even more important to fight it.
