For that one lady at the end of the video: I think it's a growing problem, and one that will only further to grow, of large segments of the population feeling like their people (white conservatives in the midwest) are dying through immigrant population growing, social issues becoming more and more liberal, and what's "in" or correct to be everything they hold dear.
Conservative values are not popular or "correct" in the media, be it television, movies, video games, sports, or anything that was once dominated by them. It's a stark difference, and with Trump the divide between conservatives and liberals will continue to grow, which is not a good thing. Of course, this isn't to say that they're right, or that we need to go back to the old days of doings things (we don't) but a growing divide like this is not a good thing. 40% or so literally feel like they're being eliminated from their own country both economically and culturally (it's bullshit, of course) but that's not healthy for a country.
