What are you referring to with "affecting the latest fad"?

And what is "an appreciation of how and why things are different for other people"? Is that appreciation as in understanding? And what are the things that are different?

I find your use of words confusing...are you saying "it's important to understand why people believe things" or "it's important to acknowledge and respect the beliefs that other people have because they are equally valid".* The latter is multiculturalist so I assume you mean that. But I have just been arguing against that and saying that the truth is primary, and that when we treat it as such we respect other people more, and are less comfortable in our own beliefs.

*You word things in such a way that it implies both. But the second implication gets all of its apparent credibility from the truth of the first. Stated on its own it is not credible. It's the same think you do by using the word truth in quotation marks, and using "true for them" in place of "belief". Don't do that.
