Maybe you have more direct experience with this than I do, but I'm not sure I agree. I don't follow the lifestyle the author describes, but I do live in an economically and culturally comparable town in Vermont that's much smaller than Massena. The town is full of gay and lesbian couples, and it really doesn't seem to be an issue. The few racial minorities seem to be well accepted. Religion is a surprisingly small factor.
Political beliefs do divide the town, but national politics are actually less divisive than I've experienced in larger places. Trans folk do have it harder, but we seem to judge the few we have as individuals. I'm sure there are other towns where these things are much less true, but I wouldn't automatically assume it couldn't work in Massena for anyone with the right attitude. I think it would come down to the individual.
