I just caught up with this thread. Not contributing more to that diverting discussion of Trek intimate relations and related digressions, but I want to say that I'm not to put out by the issue of the dual episodes' unrepentant stereotyping of Irish mores and culture circa 1900. After all, how is the framework for the construction of these characters, their millieu, and the culture's zeitgeist, prior to those impossible algorithims doing the dirty work, established anyway?
For a period recreation such as this, does Tom, Harry, B'Elanna or whoever tap databases that pull a wealth of information from strictly primary sources(journals, diaries, memoirs, etc.) of the grinding versilmilitude of how life actually played out in the subject world? Just because it's the Federation and an enlightened future, does this mean that inputs into such holographic constructions wouldn't be likely to also be pulled, to some degree at least, from popular media representations that,perhaps not taken whole cloth, are not always critically questioned as to being legitimate source material or that that question is even necessarily of concern?
Bright and shiny as the world they inhabit is, it is still hundreds of years removed from us and it seems to me that for this reason by itself,such a holographic recreation is going to have a material amount of inaccuracy, let alone that its creator might want to smooth out some of the projection's "rough edges" so as to maximize its interactibility. In-Universe, our stalwarts might write the programs up differently if their intent was strictly for, say, academic instruction or historioraphic study of some cardinal event, but for the most part, as the saying goes, it is what it is and to expect as a matter of course anything otherwise would be to confer magical, not technological prowess to these characters.
The fact that as an audience we might predominantly respond to these images as being cloying, if not demeaning or offensive begs the question of what the logical bases are for our expectations for how things should play out in this fictional world. Now, if one wants to bring up the issue of Chakotay's ancestry and the choices made on how to represent it, well that's a whole other story that can't be fudged by citing a plot device filter that has a mediating impact has been put in the way.
Sorry if I've gone way too meta here, but I guess that's just how I run!!!
