Researching Houser's internet activity, I came across at least three references to the U.S. as a "financially failing filth farm". I find that telling. It goes to my comment about needing a scapegoat for his own financial failure and personal shortcomings.
rsbm --
I also noticed how enamored he was with this phrase. First off, let's not ignore that there is alliteration there. Part of why he repeated this phrase is because it sounded good to him. For what it's worth, most of us probably know people who repeat some of the same phrases/expressions over and over again -- and we see it here in this forum as well, considering what a broad swath of the population is represented here. He has four F-words in a row.
He starts with 'financially' -- and so it's possible that this is especially important to him. He believes that money is important -- and, well, it is.
He then mentions 'failing' -- and I have to guess that this is key for him here personally, as in some of his social media postings, he identifies himself as a 'hustler' -- as a sort of con man, which can be lucrative, but it is always risky, and perhaps his luck had run out.
He then mentions 'filth' -- which I see as a moral dimension. The way we judge people (or anything) as 'clean' or 'dirty' usually has to do with some sort of value judgment we make. Many people in majority groups consider anyone other than themselves as being dirty, ignorant of the fact that people are people and generally do what they can with respect to hygiene, grooming, housekeeping, etc. I haven't seen enough information yet to speak confidently, but I have a feeling that this guy hated women, and thought they were unclean, and I have a feeling that he targeted women in the theater. I have to think that he chose that movie because he thought women would be there -- Schumer is a very talented gal who, as a guy, I find funny, and I think that many men do as well, but I think that it's possible that more women than men find her funny, and I would guess that he would have guessed that this was a movie for the gals. (My parents are both in their mid to late 70's, and my mom loved the movie, my dad thought it was ok, but a bit potty-mouthed.)
And then he mentions 'farm'. I don't know what this might mean, but I am going to guess that 'reproduction' is part of what riles him up. Farms are not one-off businesses -- they're all about reproduction, whether it's animals reproducing or crops that give both grain for food and seed.
Good call, Bessie -- I do think that this phrase, or mantra, is significant to this person.
