I found the statement about Walla Walla's so called lack of diversity to be unfounded. Frankly, having lived in small coastal towns for the last 30 years kind of biased me. Moving to, living and working in Walla Walla, I have seen persons of every ethnic background. More so than even many cities!
I guess one has to be open to people to see what is really there. As far as the wanna be comment, this person does not embrace history, farming, blue collar work, or what it takes to make a rural community.
Sure, there is no huge world renown Theater, or Bobsled team, but, spend a little time downtown meeting folks-like I have. Go to a church, a library, or to the colleges. There, amongst the people, the real folks, you'll find diverse persons of all walks of life.
If you are looking for "grungy street folks" like Portland or Seattle, that type of diversity is not in abundance, neither are haters, gangs, thugs and druggies-sorry you have tried to paint Walla Walla in a poor light. As a person of 'diversity' I feel quite at home here!
