Shuckins, "absolutely" was what I meant to emphasize.
As it was said in his and your post, "white folks" was the only context I saw. Cubans might've been implied by the cafecito thing, but I don't see that white folks couldn't take Cuban's or anyone else's place there, nor that it has to be Cuban Americans...
I agree that it's a cultural tendency, but not that it is so prevalent that you can piegonhole every "white folk" into it.. And I'm not thinking of this in a racial sensibilities perspective, I just think it's inaccurate.
Too many of the more calm and sure footed people I've known were "white", and more interested in discussing (informally and not) sex, religion, and politics, than not.. too many for that recent trend to be truly characteristic.
I think the recent trend is because of exceptional circumstances.
edit- Actually, I see what you mean. I wouldn't say it like that, but I agree.
