There are a lot of little things that can be done. The main thing is to make people aware that they cannot trust Government. A small thing that can be done (though I admit will take time) is we can stop using the term government and start using its meaning.
Govern = Control
Mente = Mind
Using proper grammar and semantics the correct way to say this is Mind Control.
Thus instead of referring to Government using the word Government we can expose and put on guard constantly the people by referring to Government by its meaning. So instead of saying Government this or that; we say Mind Control this or that.
I am sure there are thousands of other small things like this that could be used to help people stay on guard against mind control.
