That book makes sense, to a degree. Language does not tell us how to think, but it can constrain what we say. I find that our words reflect what we think, particularly when it comes to our prejudices.
Common indicators are language that is inclusive or exclusive (we/us/I Cs them/they), notions of gender (eg. Feminism indicates a prejudice toward one gender).
I have found that when someone has a biased mindset (particularly an exclusive one) and you point out their mindset through their use of language, most moderate people start to think differently and as such, their language changes.
However, I find that emotive people and political correctness break this pattern. This parallels the "faith" gambit - logic never enters the equation.
