Could we expect more political engagement from Eudora Welty?

Eudora Welty's "short" story Kin gets moving after its first two sections as the story takes on some high comedy, in a great scene that, I think, would film very well: the two cousins, Dicey (?) native Missisippian now a 20ish adult visiting home for the first time in many years, and her cousin Kate (?), go off on their visit to the elderly Uncle Felix (?), and on arrival they see a crowd of townspeople, standing on the porch, dressed up and somber. When the aunt arrives to greet the girls, Kate bursts into tears and asks: When did it happen? They (and we) assume that poor old Uncle Felix died before the girls could pay their visit - but we soon learn that, no, in fact, an itinerant photographer has set up shop in the parlor and all the country people have come by to have their portraits taken. Apparently it's nearly a once-in-a-lifetime opportunity. A good comic scene, and a great way to introduce us to the remoteness and quaintness of life in rural Mississippi early in the 20th century. As with other Welty stories, she sets a very slow and deliberate pace, so I'm not sure how she will develop this material, and she observes but seldom if ever judges - she accepts social conventions without challenge, there is virtually no commentary on the racist social structure of the era or on the privilege (all relative) enjoyed by some (all white) at the expense of others (mostly black). I know we can't expect those of another time and place to hold or even recognize the values obvious to all of us today, nor can we expect all writers to be politically bold (we can expect them to be intellectually and artistically bold), but by the time Welty was writing her late stories - the early 1950s - change was all around and we could hope that one of the great Southern writers would at least draw some attention to or inspiration from the forces of justice that were soon to upturn her world.
