Please add a setting to disable the dock moving to other screens

Besides the obvious solution of placing the Dock on one side...

You can change the delay before the Dock appears when you move the cursor to the edge of the screen.

This way if you just accidentally move your cursor to the bottom the Dock will not pop up so quickly.

Use this in the Terminal (you can use a number other than 5; this is the delay in seconds before the Dock activates when you move the cursor to its location):

defaults write com.apple.Dock autohide-delay -float 5 && killall Dock

With this, even if you accidentally bump into the edge of the screen, the Dock does not immediately show.

It becomes nearly impossible to make it appear by accident.

The most idiotic scenario: I have one external screen with a fullscreen terminal and if I move my mouse on the bottom of it, the dock moves on this screen - what the heck? I have a full-screen program open on this screen, the dock is not visible there, but my dock decides that it now wants to live behind my full screen program, instead of my main monitor? 

This makes zero sense.

Actually, it makes complete sense because when you move your cursor to the bottom of the screen you're telling the Mac that you want the dock there. Try it. Now go to your other screen and put the cursor at the bottom if it. Switches back. So, it's not a random activity, it's you telling the OS you want to move the dock. If you don't want that to happen, then don't tell the OS to do it...

Apple went out of their way to add that feature of moving the dock from monitor to monitor. That feature does not exist for the Dock on the side of the screen. I have 2 monitors one over the other, and my dock on the left side does not jump to the bottom monitor.

So it is not an accident that the dock moves when it is on the bottom of the monitor. It is intentional. And as others have pointed out, it is the actions of your mouse that cause it to happen.

Suggest using the command to increase the delay before moving as suggested by Luis Sequeira1

If they went out of their way that suggests they themselves were not convinced about it - so why not give users the option? Instead of forcing one or the other?

Because Apple does not do options. Steve Jobs was against a gazillion options and that philosophy is deeply ground into Apple. And while more options have been appearing, such as multi-button mice (only done Apple's way with a touch sensitive surface), it is unlikely Apple is going to provide options to tweak ever feature.

By all means ask via the above Feedback link, but do not hold your breath.

Feedback - macOS - Apple

You're welcome.

Something to keep in mind, as far as "...sooo many people outside of apple complain about it" goes, even if a million people complained, that's less than 1% of the total Mac users.
