No Joe, "mind control techniques" does not mean anything you want it to mean and while there may not be an Oxford dictionary definition the phrase does not mean "any kind of mental filter and (sic) either ignores or devalues information that doubts the revered truth."

So, are you suggesting that "never leave room for doubt in your mind" is NOT a mind control technique?  Of course it is.

Are you also suggesting that a belief system that does not allow for criticism of the leader isn't a "mind control technique?"

"Mind control techniques" are usually internal, not something imposed from the outside.  A kind of self-censorship, and the absolute foundation of what makes a cult a cult.
