While I wouldn't argue that it's better to avoid the issue of B'Elanna's human ethnicity than to handle it badly and resort to clichés, if the series/franchise wants credit for showing characters of various ethnicities, shouldn't they try to do it
well?
Yes, of course the terms "Latinx" and "Latin" are far too broad to really be useful descriptors, but it's not as if the series gave us any way to narrow down B'Elanna's human heritage. Even the name "Torres" is used both in Spanish and Portuguese. The only descriptor I can find for the actress's ethnicity is "Hispanic," which rules out Portuguese and suggests South or Central American heritage rather than direct descent from Europe.
I keep coming back to
@Christopher's comment, above, about how
Discovery gives the non-binary character Adira authenticity by drawing on the real-life experiences of Adira's portrayer, Blu del Barrio, also a non-binary person. Could
Voyager have given Torres's human side a credit's worth of authenticity by drawing on the real-life experiences and cultural knowledge of her portrayer, Roxann Dawson?
Or, barring that, could they at least have tried not going out of their way to make everything about her human side as unrelentingly whitebread as they did? I mean, her dad's name was John, her uncle's name was Carl, and she had three cousins named Elizabeth, Michael, and Dean. Her favorite foods were things like banana pancakes and fried chicken. She read romance novels and was good at math and athletics. Whitebread.
