They're not victims of mind-control. They're weak conformists who chose to outsource their beliefs and shut off their critical thinking in return for acceptance.

They do not want to be free from the system. They want a bigger system that can do even more of their thinking for them.

They are slaves. If you free them, they will find or create a new master. If you're not careful, they'll drag you down to slavery with them.

Luckily, they are weak and rely on pity/mercy to win. Show them none.
