Although, it does highlight a couple of things–One of which is “Don’t listen to what they say, look at what they do…”. Lots of people are going to report high-minded and nice-sounding things when asked. Far fewer are actually going to walk their talk.

As a friend of mine who has extensive time dealing with confrontational situations put it to me, “Watch their hands… Ignore their mouths; hands tell truths, mouths tell lies…”.

The other thing it highlights is the not-surprising insight that people who are motivated enough to join an organization espousing their stated beliefs are a lot more likely to actually follow through and act on those stated beliefs–Along with the reinforcing nature of hanging around with like-minded people.

Overall, mostly a restating of obvious things that should come as no surprise to any observant adult.
