Meaning of "reinforce that approach"

I am assuming that the guide is asking you to speak with that language so that others follow your lead. The guide is essentially saying: "Demonstrate that approach with the language you use."

Reinforce in this context would just mean that the guide is asking you to speak that way so that others will follow your example.

The sentence is perfectly clear to me, so I'll just explain what it means. Consider the following observation:

"The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum. That gives people the sense that there's free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of debate." - Noam Chomsky (b.1928)

Does this make it clear to you what it means for language to "reinforce" a particular approach? Some other quotations that are getting at the same idea:

"When we confine our debates to the merits or demerits of particular executive orders, we are tacitly accepting arbitrary rule." - Thomas Sowell (b.1930)

"In the animal kingdom, the rule is eat or be eaten. In the human kingdom, define or be defined. Every disagreement in the world is a matter of definition and degree." - Kaylanis Law

"The battle for the world is the battle for definitions." - Beverley Eyre

*Reinforcing that approach means that appapprch is being strengthen.for example :If govt is adopting digital means that results to reinforce various schemes. *
